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.

Initial project setup

Create a new folder for our Meme Creator application. Open up the folder in VSCode or any other text editor you are using for this project. Navigate to the folder in your terminal and run npm init. Just as we did in the previous chapter, fill in all the details asked for in the terminal, then hit Enter on Windows or return on Mac, and you will have your package.json file in the project root.

From the code files you downloaded for this book, open up the starter files folder for Chapter 2. You will see an index.html file. Copy and paste it into your new project folder. That's all for the starter files provided with this chapter, because there is not going to be a default CSS file. We are going to build the UI from scratch!

Create the files and folders we are going to use in this chapter. The folder structure should be as follows:
