Book Description

JavaScript is the programming language that all web developers need to learn. Its flexible, simple, and powerful, but knowing where to start can be intimidating. Even if you've barely touched JavaScript before, the projects in this book will have you building amazing JavaScript applications in no time.

This book takes you from beginner to winner with JavaScript. Through a series of engaging projects that showcase how easy it is for you to create great things with JavaScript, you will learn the essentials of modern JavaScript. The techniques and tools you use to build your projects are the cornerstone of professional JavaScript development, and you'll get a great grounding in all the things that count.

The first item on our JavaScript to-do list is to build a To-do list app, which you'll have done by the end of the first chapter. You'll meet DOM manipulation with JavaScript and work with event listeners, which will give you a good idea on how JavaScript works with HTML elements of your pages.

You'll work with images and text to build a Meme creator. While developing this app, you will learn about the Canvas element, used for drawing graphics. You will also learn about ES6 (ECMAScript) Classes, and be introduced to layouts using the CSS3 flexbox.

You will then build a weather application, which will show you different methods of performing AJAX requests and working with dynamic, external data.

You'll also develop a responsive Event Registration form with powerful form validation which allows users to register for your upcoming event and use charts and graphics to display registration data.

WebRTC enables real-time communication in a web browser. You'll learn how to use that as well, 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 simply throw together a blog with React, and get the sense of why this kind of JavaScript framework is used for building large scale applications. To make your blog more maintainable and scalable, you'll be using Redux to manage data across the React components.

What you will learn

• Good foundation to learn other JavaScript frameworks and libraries
• Learn the tricks of the trade like a professional JavaScript developer
• Write maintainable and scalable code by organizing functions into modules
• Use professional tools such as Node, NPM, Babel, and Webpack in your front-end development
• Work with real-time data such as incoming video stream, texts, and so on
• Use React for building large scale applications
• Use Redux to manage data across the React components which will greatly speed up the development process
