Start building beautiful web applications in JavaScript with the bestselling introduction to the language, updated with new features, fresh exercises, and fun projects.JavaScript, the programming language that allows us to add programs to web pages, lies at the heart of almost every modern web application, from social media sites to browser-based games. Just about every device can run it, making it a great choice for writing universally useful code.The fourth edition of this classic textbook takes you on a journey through the language of the web, starting from its basic elements and building up to engaging, complete programs. The author’s personal experiences from years of maintaining popular open source projects enliven the text with practical insights and examples. This edition of Eloquent JavaScript updates the book to describe the 2024 version of JavaScript, and shifts the attention given to some topics to better reflect current development practices.The text takes a practical approach to teaching, rooting theory in plenty of motivating examples. The first half of the book describes the fundamentals of the language, whereas the second half shows how to apply it in two programming environments: the web browser and Node.js. Five project chapters show how to build bigger programs, working through these projects in a piecemeal, conversational way. They include a pathfinding robot, a small programming language, a platform game, a pixel drawing program, and a simple dynamic website.Exercises provided at the end of most chapters will challenge you to creatively apply the concepts and techniques introduced. The book’s companion website provides an interactive environment for working on these exercises and playing with the example programs.Whether you’re looking to learn JavaScript or to deepen your programming skills, you’ll find this book full of stimulating material.Updated to ECMAScript 2024 Read more

Start your journey towards becoming a JavaScript developer with the help of more than 100 fun exercises and projects.Purchase of the print or Kindle book includes a free eBook in the PDF format.Key FeaturesWrite eloquent JavaScript and employ fundamental and advanced features to create your own web appsInteract with the browser with HTML and JavaScript, and add dynamic images, shapes, and text with HTML5 CanvasBuild a password checker, paint web app, hangman game, and many more fun projectsBook DescriptionThis 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 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 code.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. This will be supplemented with a brief crash course on HTML and CSS to illustrate how JavaScript components fit into a complete web application.As 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. 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 learnUse logic statements to make decisions within your codeSave time with JavaScript loops by avoiding writing the same code repeatedlyUse JavaScript functions and methods to selectively execute codeConnect to HTML5 elements and bring your own web pages to life with interactive contentMake your search patterns more effective with regular expressionsExplore concurrency and asynchronous programming to process events efficiently and improve performanceGet a head start on your next steps with primers on key libraries, frameworks, and APIsWho this book is forThis book is for people who are new to JavaScript (JS) or those looking to build up their skills in web development. Basic familiarity with HTML & CSS would be beneficial.Whether you are a junior or intermediate developer who needs an easy-to-understand practical guide for JS concepts, a developer who wants to transition into working with JS, or a student studying programming concepts using JS, this book will prove helpful.Table of ContentsGetting Started with JavaScriptJavaScript EssentialsJavaScript Multiple ValuesLogic StatementsLoopsFunctionsClassesBuilt-In JavaScript MethodsThe Document Object ModelDynamic Element Manipulation Using the DOMInteractive Content and Event ListenersIntermediate JavaScriptConcurrencyHTML5, Canvas, and JavaScriptNext StepsAppendix – Practice Exercise, Project, and Self-Check Quiz Answers Read more
