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.

  • Container

The container is further divided into three sections:

  1. First, create-room-area, which contains the input fields needed to create a new room with a room name.
  2. Second, info-area, which contains the information regarding the room (room name and room URL). It also has two buttons that are going to be used to copy the room URL (currently hidden using the .hidden Bootstrap style class).
  3. Finally, video-area, which is used to display the videos of all the participants.

First, add the following code in src/css/styles.css file to prevent the container section from overlapping with the navigation bar:
