If you enter a web page and it asks you to accept cookies and you click OK, the popup disappears. If you have used a web browser, such as Chrome, Firefox, Safari, or Edge, then you definitely have. It is not unlikely that you have used functionality written in JavaScript. The server side of an application is the backend logic that usually runs on computers in data centers and interacts with the database, while the client side is what runs on the device of the user, often the browser for JavaScript. Excellent choice! JavaScript is a programming language that can be used on both the server side and client side of applications. It appears you have decided to start learning JavaScript. 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. This will be supplemented with a brief crash course on HTML and CSS to illustrate how JavaScript components fit into a complete web application.Īs you learn the concepts, you can try them in your own editor or browser console to get a solid understanding of how they work and what they do. The book uses 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. These include data validation, manipulating the appearance of web pages, working with asynchronous and concurrent code. JavaScript from Beginner to Professional focuses on key programming concepts and Document Object Model manipulations that are used to solve common problems in professional web applications. 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. 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.
