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.

Real-Time Video Call App with WebRTC

Hey! Just to let you know, the JS Meetup was a great success after getting a backend developer to complete the serverside of the application. But you did great completing the entire frontend of the application. You created a complete Event Registration website, which lets users sign up the events, while learning some really important concepts, such as building reusable ES6 modules, making AJAX requests while handling asynchronous code using Promises, creating beautiful charts out of data, and of course, the classic form validation with a validation service.

The backend code was also written with JavaScript (Node.js), so you might really be interested in writing serverside code. But sadly, as I mentioned earlier, Node.js is beyond the scope of this book. Actually, you can do some really cool things with plain JavaScript, although many people...
