JavaScript by Example

By: Dani Akash S

Overview of this book

JavaScript is the programming language that all web developers need to learn. The first item on our JavaScript to-do list is building g a To-do list app, which you'll have done by the end of the first chapter. You'll explore DOM manipulation with JavaScript and work with event listeners. You'll work with images and text to build a Meme creator. You will also learn about ES (ECMAScript) classes, and will be introduced to layouts using the CSS3 Flexbox. You'll also develop a responsive Event Registration form that allows users to register for your upcoming event and use charts and graphics to display registration data. You will then build a weather application, which will show you different ways perform AJAX requests and work with dynamic, external data. WebRTC enables real-time communication in a web browser; you'll learn how to use it when you build a real-time video-call and chat application later in the book. Towards the end of the book, you will meet React, Facebook's JavaScript library for building user interfaces. You'll throw together a blog with React, and get a feel for why this kind of JavaScript framework is used to build large-scale applications. To make your blog more maintainable and scalable, you'll use Redux to manage data across React components.

Hey! Good work with the Video Call app. Hope you made some calls to your friends. In the previous chapter, we built a Video Call app using the SimpleWebRTC framework. Isn't it great to know that you can build all these cool applications with JavaScript? You have the power to access the user's device hardware straight from the browser.

So far, you have been building entire applications by yourself, so you had complete knowledge of the app's structure, such as the classes and IDs used in HTML and CSS and the classes, functions, and services used in JavaScript. But in the real world, you seldom work alone. If anything, you work in teams of sizes ranging from a few members to hundreds of developers working across the globe. In this case, you will not have knowledge about the entire web application. For this chapter, you are part of a huge...
