While front-end development focuses on the user interface, back-end development is what drives a website or application. It's everything behind the scenes that users don't see but is essential for the operation of a site—from database interactions and server management to application logic and API integration. Backend developers use languages like Python, Ruby, Java, and JavaScript (with Node.js) to build the server-side components that ensure the application works smoothly and efficiently.

Core responsibilities of a Back-end Developer include:

Introduced by Netscape in 1995, the original version of JavaScript was never intended to be a back-end programming language. JavaScript’s original designers wanted to create a lightweight scripting language that would enable the Netscape Navigator browser to display dynamic web experiences. However, now it has become a powerful tool in backend development through the use of Node.js. 

Node.js allows developers to use JavaScript to write server-side code, providing a unified language for both the front and back ends of a web application. This enhances development efficiency, reduces context switching, and allows for the use of JavaScript's ecosystem of libraries and frameworks. You can revise its basics from the JavaScript Foundations chapter again!

Intro to Back-end Development

Understand the importance and functions of a back-end developer and learn basics of APIs and databases.

Have you ever wondered how websites like Letterboxd let you see movie reviews and ratings so smoothly? It’s all because of APIs. APIs or Application Programming Interfaces are a set of rules that allow one piece of software to interact with another. Think of an API as a waiter in a restaurant. When you request to see movie reviews, you’re sending an order through the waiter to the kitchen, which is the server. The server then gets your food (response) back, after sending your request to the kitchen. 

, a framework for network communication, to understand the flow:

: This layer represents the software applications that interact with the API, like the Letterboxd website. 

: This layer prepares data for transmission across the network. When interacting with an API, it might encode or compress the request data. 

: This layer establishes and manages communication sessions between the application and the API server. 

: This layer breaks data into packets and ensures reliable delivery of those packets between the application and the server. It handles retransmission if necessary. 

 This layer determines the best route for data packets to travel across the network to reach the API server. 

: This layer adds error detection mechanisms to data packets and ensures reliable transfer between network devices. 

: This layer handles the physical transmission of data packets over the network medium (e.g., cables or Wi-Fi).

APIs come in different types, each suited for specific needs. The two main types we’ll discuss are REST and SOAP.

 REST is a widely-used architectural style for designing networked applications. is a common way to design how different software systems talk to each other over the internet. RESTful APIs use standard HTTP methods to perform actions on resources, making them straightforward and easy to use. Here are the main HTTP methods used in RESTful APIs:

SOAP is another protocol for web services that rely on XML-based (eXtensible Markup Language) messaging. It is more rigid and protocol-heavy compared to REST but offers robust security features, making it suitable for enterprise environments. SOAP APIs are designed for complex transactions and require a strict contract between client and server.

Developers often need tools to test and develop APIs efficiently. One such tool is Postman. Imagine you’re a chef experimenting with new recipes before adding them to the menu. Postman is a tool that allows developers to test and develop APIs. It lets you send requests, view responses, and ensure everything works correctly, just like a chef perfecting a dish before serving it to customers. With Postman, developers can easily create and test API requests, ensuring that each endpoint functions as expected and returns the correct data.

 are essential indicators of the outcome of HTTP requests made to web servers, including when interacting with APIs. They provide information about whether a request was successful, encountered an error, or needs further action.

Application Programming Interfaces (APIs)

Follow the API interaction process within the OSI Model, from user request to server response, illustrating how data flows through each layer to facilitate communication and retrieve requested information.

We have often seen daunting visuals of techies in sci-fi movies saving the world with their screen beaming with 0s and 1s. They make your SDE-IIs look like heroes who have a world of their own, each having a separate purpose in this world. While a lot of the engineers you work with 

 have a separate outcome they work towards, somehow when you try to peep into their screens you see much more than 0s and 1s. 

Being a Product Manager in this day and age where everyone is running towards the best tech for their product may be daunting. If you are someone who has been running away from the bubble that these tech folks have created for themselves, you might be wondering about the correct starting point to acquaint yourself with it. It is not easy with the overwhelming number of resources out there to help you demystify the jargon of and around tech.

This foundational guide is about to do just that for you. Welcome to the A-Z of tech terms you hear almost everyday. We hope this becomes your go-to document to help you de-stress before the next stand-up call with the tech team.

By the end of this guide, you will know the basics of how the web operates, front-end development, and back-end development. While you might not gain the skills required to take up your product's tech entirely on your own, you will know how to:

Learning is tough. It takes effort. Lots of it. It's not easy to pull the brakes on your work or life and sit down to learn when you have the option to spend your time in a million other ways.

Outcomes from Tech Foundations

Brief introduction of the curriculum and the outcomes from this guide!

Back to Basics

Understand how computers read data and how the web work at large.

Let's start our tech journey from the beginning and dive into key concepts which will help us understand how computers, operating systems, applications, and the web work together. This foundational knowledge will enable us to grasp the intricacies of the digital world and make informed decisions in our tech interactions.

Computer, Operating Systems and Applications

Contrary to popular opinion, a computer isn't just the dusty machine on your working desk. Your phones, laptops, tablets, gaming consoles etc. are all computers. Imagine the computer as the ultimate multitasking tool: a device that can perform countless tasks, from crunching numbers to displaying vibrant graphics. It's essentially a machine that processes data according to a set of instructions. Think of it as your digital assistant, which has the power of handling everything from creating documents to browsing the internet.

If the computer is your digital assistant, the Operating System is its brain. As the name suggests, it quite literally helps 

 it. It's the software that manages all the hardware and other software on your computer. It handles everything from running applications to managing files and connecting to the internet.

Applications (read: apps) are the programs that perform specific tasks for you. They can be anything from word processors and web browsers to games and email clients.

Imagine you’re looking at a huge metropolitan. The internet is pretty much like that—it's a vast network of all the buildings, towers, and skyscrapers. Our applications live in each of these buildings and instead of bricks and mortar, we have data and servers creating our digital structures.

Data? What is that, you ask? Data is any collection of information that can be processed by a computer. It encompasses a wide variety of types and forms, including text, numbers, images, audio, and video. Everything that we see, listen and feel is data. How does this data work though? To understand further how data works in computing, we need to delve into its most fundamental units: bits and bytes.

Bits, Bytes, 0s and 1s: How Computers Read Data

Think of bits and bytes as the fundamental building blocks, much like the clay and concrete that form a brick (data!). A bit is the smallest unit of data in a computer. It can have one of two values: 0 or 1. These values are binary, meaning they represent two possible states—much like a light switch being either on (1) or off (0).

A byte is a group of 8 bits. Think of a byte as a small, manageable chunk of mixture. While constructing your skyscraper, each construction worker will work on a given task for which they need instructions which are as clear and precise as they can be. Similarly, your computer—which can accept data in the form of images, text, videos, or audio—needs to process said data to act on your precise instruction(a series of 0s and 1s).

When you perform any action on your computer—like typing a letter, watching a video, or running a program—your computer translates these actions into binary code. These 0s and 1s are processed by the computer’s CPU (Central Processing Unit) to carry out your instructions.

There are different ways in which computers read these varied forms of data:

On the construction site of your skyscrapers, you don’t deliver all the materials in one giant heap. Instead, you bring in smaller, manageable loads of bricks, cement, and steel. Similarly, data on the internet is broken down into smaller pieces called packets. These packets are like your building materials, each containing a part of the information needed to complete the project. They are each a small segment of a larger message and once your computer receives them, it recombines the full instruction.

Web Page, Web Server, Web Browser, Search Engine

 A domain name is a human-readable address used to identify a website on the internet, such as 

. Domain names make it easier for people to remember and access websites without needing to know the numerical IP addresses.

DNS: DNS servers, are like phone directories and operators at a call center. In older times, when you had to contact a specific person or business, you would look up their phone number in the directory or ask an operator. Similarly, DNS servers translate human-friendly domain names (like 

) into IP addresses, guiding your data to the right server. Each device connected to the Internet has a unique IP address, which other machines use to find the device. DNS servers eliminate the need for humans to memorize these numerical addresses, making it easier to navigate the internet using simple, memorable domain names.

Cloud Networking: Off-Site Storage and Resources

 Think of these as large libraries located around the world. Each library houses a vast collection of books (data) and resources (computing power) that can be accessed by anyone with a library card (internet connection).

 This is like having a personal bookshelf at home. It has limited space and resources compared to a large library. While you can store some books and resources, it's not as extensive or flexible as using the libraries.

 Imagine virtual storage space as additional shelves in these libraries where you can keep your personal collection of books. You don't need to have a large bookshelf at home because you can store your books in the library and access them anytime.

Cloud networking involves utilizing remote servers hosted on the internet to store, manage, and process data, rather than relying solely on local infrastructure. Cloud services such as AWS (Amazon Web Services), Azure, and Google Cloud act as off-site storage facilities for digital data and computing resources to be stored securely and accessed remotely. They provide virtual storage space and computational power. This helps reduce the need for extensive on-site storage and allows for flexible resource allocation as needed.

Web Basics

Gain an understanding of how computers function as versatile tools and how the web works at large!

Problem solving is the cornerstone of software development. It's the fundamental task taken by programmers and programming languages are just aids in this process. Therefore, this becomes an invaluable skill for anyone to have before they start coding.

Many new programmers find problem solving the hardest skill to build. They may quickly learn syntax and basic concepts but struggle when facing an open-ended problem. The best way to improve is through practice—building lots of programs and learning from each experience.

Let's break this process down into three key steps:

Problem-Solving

Break the problem-solving process down into easy-to-understand steps and learn how programmers use pseudocodes to chalk their plan out.

Intro to Front-end and HTML Foundations

Learn the importance of front-end development and dive into the basics of HTML!

Front end development is the process of creating the part of a website that users interact with directly. It's everything you see and experience on a website—from text and images to buttons and menus. Front end developers use a combination of HTML, CSS, and JavaScript to build the user interface and ensure it works smoothly.

The primary objectives of front-end development are as follows:

Popular Frameworks/Libraries for Front-end Development

A library is essentially a set of reusable modules or functions that are designed to be integrated into larger software projects. It provides a convenient way to access commonly used operations or algorithms, saving developers time and effort by abstracting complex tasks into simpler, reusable components. Libraries are modular and can be integrated into various parts of an application as needed.

Imagine you are building a house, and you have a toolbox filled with various tools such as hammers, screwdrivers, saws, and measuring tapes. Each tool in the toolbox represents a library. These tools are highly specialized and designed to perform specific tasks. You can use them whenever you need, in whatever order you prefer. You have full control over the construction process and decide how to use each tool to build different parts of the house.

Unlike libraries, frameworks provide a complete solution, offering a structured way to build applications from start to finish. The framework is in control and it calls the developer's code at specific points, often following a defined lifecycle.

 used for building user interfaces (UIs) in web applications. Developed and maintained by Facebook, React has gained popularity for its component-based architecture and efficient rendering capabilities. Here are the key aspects of React:

Angular is a JavaScript framework for building web and mobile applications. Developed by Google, Angular is a full-fledged platform that includes everything needed to build complex client-side applications. Here are the key aspects of Angular:

Introduction to Front-End Development

Get equipped with the foundational knowledge necessary to create and understand basic HTML documents, setting the stage for further exploration into web development.

HTML (HyperText Markup Language) is the standard language used to create the structure of web pages. Think of it as the skeleton of your website, defining where content goes and how it's organized. It tells the web browser what each part of the page is—whether it’s a heading, a paragraph, a link, or an image. It quite literally label pieces of content such as "this is a heading", "this is a paragraph", "this is a link", etc. It’s a combination of Hypertext, which defines the link between web pages, and Markup language, which is used to define the text document within tags to structure web pages.

Tags are the building blocks of HTML. They direct your web browser on how to format and display your web page. They are enclosed in angle brackets like 

. Each tag usually comes in pairs: an opening tag 

. The closing tag has the same text as the opening tag, but has an additional forward-slash ( / ) character. There are more than 140 HTML tags in all. 

An HTML element includes a start tag, some content, and an end tag. For example:

This is an HTML element with a <p> tag and some text inside. HTML elements are building blocks of web pages, representing different types of content such as headings, paragraphs, links, and images.

Including closing tags for HTML elements is crucial for ensuring that your web content is displayed correctly. While modern browsers can often handle missing closing tags, adhering to best practices by always including them helps maintain clean, predictable, and maintainable code. Moreover, sometimes the behavior of code may be unexpected and give you undesirable results. The HTML elements without any content are called empty elements. These do not require an end tag.

Great! You've now learnt how to read (and maybe write!) a simple Hello, World web page. Let's now see where to write these code segments and how to view your first HTML page.

Web pages can be created and modified by using professional HTML editors. You can learn how to set your environment up from 

 about HTML elements (even empty elements). They are always included in the opening tag of an element and usually come in name/value pairs like 

 attribute, in this example, provides additional information about an element. This information is often displayed as a tooltip when the user hovers over the element (a paragraph, in this example).

Now that you've got a basic understanding of HTML, let's dive into one of the most fundamental parts of web development: working with text. In this section, we'll cover how to create and format different types of text elements in HTML.

Creating a paragraph in HTML is super straightforward. You use the 

 tag to define a paragraph. Here's an example:

When you open this in your browser, you'll see a block of text with some spacing (margin) before and after it. This spacing is added by default to make paragraphs look distinct from each other.

Headings are used to define the titles and subtitles on your webpage. HTML provides six levels of headings, from 

 being the most important (and largest) and 

 being the least important (and smallest). Here’s how you create them:

When viewed in your browser, these headings will appear in different sizes, helping to structure your content hierarchically.

Browsers automatically add some white space (a margin) before and after a heading.

Comments are useful for adding notes to your HTML code. These notes are not displayed in the browser but can be very helpful for anyone reading the code, including your future self! To add a comment, you use the 

Comments are great for explaining why certain parts of your code are there or reminding yourself of things you need to come back to later. The also help in improving readability. Remember that a well documented code is not just great for your reference but helps keep your whole team in sync.

HTML Foundations: Part I

Learn how attributes enhance HTML elements by providing additional information.

Now that we've covered how to format text, let's move on to another essential part of web development: 

 and images. These elements help create a more dynamic and interactive user experience. Here, we'll explore how to create links to different web pages and how to display images on your site.

How to Create Links to Pages on Other Websites

Creating a link to another website is simple with the 

 attribute to specify the URL of the page you want to link to. Here's an example:

HTML links are hyperlinks, you can click on a link and jump to another document. When you move the mouse over a link, the mouse arrow will turn into a little hand.

By default, links will appear as follows in all browsers:

How to Create Links to Other Pages on Your Own Website

You can also create links to other pages within your own website using the same 

 tag. If your site has a folder structure, you'll use relative paths to navigate between pages. Here's how you link them:

These links would navigate to the "about.html" and "contact.html" pages located in the same directory (folder) as the current page.

How to Display an Image on a Webpage Using HTML

 tag, which is an empty element (it doesn't have a closing tag). Images are not technically inserted/embedded into a web page; images are 

 attribute to specify the path to the image file and the 

 attribute to provide alternative text that describes the image. Here's an example:

 tag. This helps in accessibility and ensures that users understand the content of the image even if it cannot be displayed.

You can also use absolute URLs for images hosted on other websites:

This will display the image from the GrowthX website.

In HTML, elements are categorized into two main types based on their display behavior: block-level and inline elements.

A block-level element always starts on a new line and occupies the full width available within its parent container. These elements by default stretch out horizontally to fill the available space and have vertical margins (space) added above and below them by browsers, which helps visually separate different content blocks.

 element defines a paragraph of text, while the 

 element defines a division or a section within an HTML document.

In contrast to block-level elements, inline elements do not start on a new line and only occupy as much width as necessary for their content. They are typically used within paragraphs of text to style or mark up smaller sections without disrupting the flow of surrounding text. Inline elements are versatile for adding emphasis, links, or small icons within paragraphs or other inline content. They do not add vertical margins by default and flow within the text or other inline elements.

HTML Foundations: Part II

Learn how to enhance web pages with interactive links and visually engaging images, ensuring a more dynamic and user-friendly online experience.

CSS Foundations

CSS is what gives your HTML pages their look and feel. This chapter will walk you through the how's of CSS and help you build beautiful web pages!

HTML was originally designed to structure and define the content of web pages. Tags like 

for paragraphs were only meant to outline the hierarchy and structure of information. However, as the web evolved, there was a need to add more visual styles directly into HTML, such as with the 

 attributes. This approach caused several issues:

Formatting, thus, became a long and expensive process.

To address these challenges, the World Wide Web Consortium (W3C) introduced CSS, or Cascading Style Sheets. CSS separates the presentation styles (like fonts, colors, layouts) from the content structure defined in HTML. By using CSS, web developers gained greater control over the visual presentation of web pages while maintaining the semantic integrity of HTML for content. The style definitions are normally saved in external .css files. With an 

 file, you can change the look of an entire website by changing just one file! This approach not only streamlined development but also improved the user experience and accessibility of websites across different devices and browsers.

CSS is what gives your HTML pages their look and feel. It controls how elements like headings, paragraphs, and images appear on your website by defining their colors, fonts, sizes, spacing, and more. It saves a lot of work and can control the layout of multiple web pages all at once.

A CSS rule is a fundamental structure used in CSS to define how HTML elements should be styled on a web page. It consists of two main parts:

 heading elements (the selector) will be blue in color and center-aligned (as described in the declaration block).

There are multiple types of selectors based on their states, attributes, class, id etc. For the sake of simplicity of this guide, let's dive deep into the CSS element, class and id selectors.

Now, if you want the header to be white and the introduction content to be red:

Rules and Selectors

Understand the components of a CSS rule, including the selector and the declaration block.

The cascade is the algorithm for solving conflicts where multiple CSS rules apply to an HTML element. Imagine you have a mood board for your website design, and the cascade is like the decision-making process to figure out which styles get the final say.

The cascade algorithm is split into 4 distinct stages:

Inheritance is the mechanism by which certain CSS properties of a parent element are passed down to its child elements. Not all properties are inherited by default, but many are. Examples of inheritable properties include 

When no value for an inherited property has been specified on an element, the element gets the computed value of that property on its parent element. Let's look at an example:

 specified, we see that it is magenta in color. This is inherited from the 

For non-inherited properties, however, if no value is specified on an element, the element gets the initial value as defined in the property's specification. Let's look at an example using the 

t does not have a separate border around it.

In CSS, the Box Model is used to define how the size and spacing of HTML elements are calculated and rendered on a webpage. Understanding the box model is crucial for controlling the layout and design of your web pages. The CSS box model is essentially a box that wraps around every HTML element. It consists of: content, padding, borders and margins. Let's dive deeper into each component of the box model and how it affects the layout of elements.

In order to set the width and height of an element correctly in all browsers, we need to know how they are calculated using the Box Model.

Note: When you set the width and height properties of an element with CSS, you just set the width and height of the 

. To calculate the total width and height of an element, you must also include the padding and borders.

To calculate the total size of an element, you need to add the width and height of the content, padding, border, and margin:

Total Width: 200px (content) + 40px (padding) + 10px (border) + 20px (margin) = 270px

Total Height: 100px (content) + 40px (padding) + 10px (border) + 20px (margin) = 170px

The Cascade and Box Model

Gain essential insights into how CSS resolves conflicts and passes styles between elements, and learn about the Box Model.

JavaScript Foundations

Dive into JavaScript foundations and master the essentials of the language that powers the web!

JavaScript is an essential component of the triad of core web technologies, often described as the "layer cake" of web development. This triad consists of HTML, CSS, and JavaScript:

JavaScript is a scripting or programming language that empowers web developers to create interactive and dynamic features on web pages. Whenever a web page does more than just present static information—such as updating content in real-time, providing interactive maps, displaying animated graphics, or incorporating video playback functionality—JavaScript is typically the technology driving these features.

 in JavaScript (and in most programming languages) is a symbolic name associated with a value and whose associated value can be changed. They also provide a way of labeling data with a descriptive name, so our programs can be understood more clearly by the reader and ourselves. It is helpful to think of variables as containers that hold information. You can declare a variable using the 

When naming variables, it's important to follow certain rules. Variable names must begin with a letter, an underscore (_), or a dollar sign ($). After the first character, they can include letters, digits, underscores, and dollar signs. Variable names are case-sensitive, meaning myVar and myvar would be considered different variables. Also, you cannot use JavaScript reserved keywords as variable names, such as 

What do each of these operators stand for?

Variables and Operators

Cover the fundamentals of variables and operators in JavaScript, essential for understanding how data is manipulated and processed in programs.

Imagine you're making a card for your friend and you forget their age. You take the card to work the next day, with space left for writing their age, and ask your other friends. As soon as you get to know it, you take your pen and fill it out on the space left on your card. This is equivalent to embedding a variable in a string (like a placeholder as explained above) and filling it out with a value later. Let's check this out:

Template Strings/Literals provide an easy way to interpolate variables and expressions into strings. Using this simple example, you can understand their use and syntax!

Let's take the example of you making a birthday card. Say you start printing template cards for your family and friends. You would now segment these cards on the basis of their age, where kids below 15 would get a certain kind and everyone above 15 would get a more adult-like card. This is precisely what conditionals in JavaScript (and programming in general) are. They are used to make decisions based on specific conditions. They control the flow of a program by executing different code blocks based on whether a specified condition evaluates to true or false:

Certain tasks—like updating a variable's value, performing an action as long as some condition is true, stopping an action once a condition becomes true—need to run repetitively. This done in programming by using loops. Loops in JavaScript are control structures that allow you to execute a block of code multiple times, typically with different values.

There are several types of loops in JavaScript, each suited for different situations:

This loop iterates from 1 to 5 (inclusive) and logs each number to the console.

This loop continues to log numbers as long as the number is less than 10.

Nesting in programming refers to placing one construct inside another. In JavaScript, this often involves placing conditionals or loops inside other conditionals or loops to create complex decision-making or repetitive structures.

Imagine you are building a simple program to determine if a person can attend a restricted movie based on their age and if they have a guardian present. Here is how you could use a nested conditional:

These are exactly what they sound like. Truthy values are those which evaluate to 

 in a boolean condition and Falsy values evaluate to 

In JavaScript, the following values are considered falsy:

Everything else is a truthy. An easy way to remember is that everything with a "value” is truthy and everything without one is falsy. Let's take examples:

Data Types, Conditionals, and more

Learn about the 8 fundamental data types in JavaScript.

In real life, objects are tangible items like houses, cars, people, and animals. These objects have attributes (properties) and behaviors (methods) that define their characteristics and actions. In JavaScript, we can emulate real-world objects using JavaScript Objects. They allow us to store, organize, and manipulate data efficiently.

 object which has the following four properties:

Let's discuss 2 of the many ways to create an object:

As we've already seen, these objects have a number of properties associated with them. In order to access these properties, which basically involves retrieving or updating the values, we have two common notations:

You can learn more about JavaScript Objects 

Imagine an array in JavaScript to be like a row of ducks lined up in a neat order. Each duck has a specific spot in the row, and you can easily find a particular duck based on its position. This is similar to how arrays work: they are used to store multiple values in a single variable, where each value is called an element and each element has a unique index (position) starting from 0.

Let's start by understanding the syntax of creating an array of ducks:

 is an array containing four elements. The first duck (

You can access and manipulate the ducks (elements) in the array using their indices:

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's commonly used for transmitting data in web applications. Imagine you have a bookstore and you want to keep track of your inventory in a digital format that can be easily shared with others or processed by a computer system. JSON provides a structured way to represent this data.

JSON is commonly used in web development to exchange data between a web server and a client-side application (like a browser). For example, when a bookstore's website requests information about available books from a server, the server might respond with JSON data similar to the example above. This JSON data can then be parsed and displayed dynamically on the website. It is also used for storing configuration settings, transmitting data in IoT (Internet of Things) devices, and exchanging data between different applications and platforms.

JSON exists as a string — useful when you want to transmit data across a network. It needs to be converted to a native JavaScript object when you want to access the data. This is not a big issue — JavaScript provides a global 

 object that has methods available for converting between the two.

JavaScript Objects

Explore how JavaScript Objects emulate real-world entities with properties and methods. 

A JavaScript function is a block of code designed to perform a particular task. It is executed when something invokes (calls) it. It can take inputs, process them, and return an output. Functions allow you to encapsulate logic, making your code more modular, reusable, and easier to maintain. It is defined using the 

 keyword, followed by a name and parentheses. The parentheses may include parameter names separated by commas. Here’s the basic syntax:
