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.

Good work! You have built a Meme Creator that will now convert your images into memes. More importantly, you have a great development environment that will make app development with JavaScript even easier. Let's review the things you have learned in this chapter:

  • A short introduction to the flexbox layout system in CSS
  • An introduction to JavaScript modules
  • Module bundling with Webpack
  • Production optimizations to improve performance for users
  • Using HTML5 canvas with JavaScript to draw graphics on a website

We learned quite a lot in this chapter. Especially about Webpack. It might seem a little overwhelming, but it is very useful in the long run. In the next chapter, we are going to see how to write modular code and reuse it across the application, which is now possible due to Webpack.
