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.

Congratulations! You have built your first JavaScript application with the new ES6 syntax. You have learned the following concepts in this chapter:

  • DOM manipulation and event listeners in JavaScript
  • ECMAScript 2015 (ES6) syntax of JavaScript
  • Chrome Developer Tools
  • The workings of Node and npm
  • Using Babel to transpile the ES6 code to ES5 code

In our current npm setup, we have simply created a compile script to transform our code into ES5. There are lots of other tools available to automate more tasks, such as minification, linting, image compression, and so on. We will use one such tool called Webpack in our next chapter.
