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.

Introduction to WebRTC

Before we start building the application, it's best to know a few things about WebRTC so that you get a good idea about the workings of the app.

History of WebRTC

Real-time communication capabilities have become a common feature of many of the applications we use nowadays. Say you want to chat with your friend or watch a live soccer game. Real-time communication is a must for these applications. However, having live video calls on a browser in the past was quite a difficult task for users, because they had to install plugins into their system for different applications to use video calling on the web browser, and with plugins came vulnerabilities, hence, regular updates.
