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.

Summary

Hopefully, you had a great time building the Video Call application. In this chapter, we did some new things with JavaScript and learned some new concepts, such as JavaScript WebRTC APIs and the SimpleWebRTC framework. Along the way, we did lot of cool things, such as manipulating browser history, selecting text using JavaScript, and working with URLs. Also, we shortened some of our code with short-circuit evaluation and learned about setters and getters for manipulating class variables in JavaScript.

SimpleWebRTC comes with many other events and actions which allow you to do more in the app, such as mute your microphone, mute audio from others, and so on. If you are interested, you can check out the SimpleWebRTC home page for more examples.

We know how to create reusable JavaScript modules, which we did in the previous chapter. In the next chapter, we are going to take...
