JavaScript from Beginner to Professional (1 ed)

Start your journey toward becoming a JavaScript developer with the help of more than 100 fun exercises and projects.

This book demonstrates the capabilities of JavaScript for web application development by combining theoretical learning with code exercises and fun projects that you can challenge yourself with. The guiding principle of the book is to show how straightforward JavaScript techniques can be used to make web apps ranging from dynamic websites to simple browser-based games.

JavaScript from Beginner to Professional focuses on key programming concepts and DOM (Document Object Model) manipulations that are used to solve common problems in professional web applications. These include data validation, manipulating the appearance of web pages, working with asynchronous and concurrent codes, and much more.

The book follows project-based learning to provide context for the theoretical components in a series of code examples that can be used as modules of an application, such as input validators, games, and simple animations. This will be supplemented with a brief crash course on HTML and CSS to illustrate how JavaScript components fit into a complete web application.

Practice the concepts in your editor or browser console to understand how they work. By the end of this JavaScript book, you will feel confident writing core JavaScript code and be equipped to progress to more advanced libraries, frameworks, and environments such as React, Angular, and Node.js.

What You Will Learn:

• Use logic statements to make decisions within your code.
• Save time with JavaScript loops by avoiding writing the same code repeatedly.
• Use JavaScript functions and methods to selectively execute code.
• Connect to HTML5 elements and bring your own web pages to life with interactive content.
• Make your search patterns more effective with regular expressions (regex).
• Explore concurrency and asynchronous programming to process events efficiently and improve performance.
• Get a head start on your next steps with primers on key libraries, frameworks, and APIs.
