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.

Summary

This book is designed to help you understand the basics of React. Since we only built a simple application in this chapter, we didn't get to explore many of React's cool features. In this chapter, you started off with a simple counter, then built a ToDo list in the React crash course, and finally, built a simple blog application using the create-react-app tool and some libraries, such as react-router and reactstrap.

Being a simple view layer of the app, React does need a few libraries used together to make it work like a full fledged framework. React isn't the only JavaScript framework out there but React definitely is a one of a kind library that is revolutionizing modern UI development.

Everything is really great about React and the blog application we just built, except that each of the pages in the blog takes an annoying 3 seconds to load. Well, we...
