Javascript Allong

JavaScript Allongé solves two important problems for the ambitious JavaScript programmer. First, JavaScript Allongé gives you the tools to deal with JavaScript bugs, hitches, edge cases, and other potential pitfalls. There are plenty of good directions for how to write JavaScript programs. If you follow them without alteration or deviation, you will be satisfied. Unfortunately, software is a complex thing, full of interactions and side-effects. Two perfectly reasonable pieces of advice when taken separately may conflict with each other when taken together. An approach may seem sound at the outset of a project, but need to be revised when new requirements are discovered. When you “leave the path” of the directions, you discover their limitations. In order to solve the problems that occur at the edges, in order to adapt and deal with changes, in order to refactor and rewrite as needed, you need to understand the underlying principles of the JavaScript programming language in detail. You need to understand why the directions work so that you can understand how to modify them to work properly at or beyond their original limitations. That’s where JavaScript Allongé comes in. JavaScript Allongé is a book about programming with functions, because JavaScript is a programming language built on flexible and powerful functions. JavaScript Allongé begins at the beginning, with values and expressions, and builds from there to discuss types, identity, functions, closures, scopes, and many more subjects up to working with classes and instances. In each case, JavaScript Allongé takes care to explain exactly how things work so that when you encounter a problem, you’ll know exactly what is happening and how to fix it. Second, JavaScript Allongé provides recipes for using functions to write software that is simpler, cleaner, and less complicated than alternative approaches that are object-centric or code-centric. JavaScript idioms like function combinators and decorators leverage JavaScript’s power to make code easier to read, modify, debug and refactor, thus avoiding problems before they happen. JavaScript Allongé teaches you how to handle complex code, and it also teaches you how to simplify code without dumbing it down. As a result, JavaScript Allongé is a rich read releasing many of JavaScript’s subtleties, much like the Café Allongé beloved by coffee enthusiasts everywhere.

Explains how to use the programming language to add interactivity and animation to Web sites, covering image swaps, functions, frames, cookies, alarms, frames, shopping carts, and Ajax.

Responding to reader feedback, the author has thoroughly revamped the book with more step-by-step coverage of JavaScript basics, an exclusive focus on Internet Explorer, and many complete sample scripts Updated to cover JavaScript 1.5, the latest release of this popular Web scripting language Using lots of examples, including a sample working Web site, the book shows how to create dynamic and interactive pages, build entire sites, and automate pages

This is an exciting time to learn JavaScript. Now that the latest JavaScript specification—ECMAScript 6.0 (ES6)—has been finalized, learning how to develop high-quality applications with this language is easier and more satisfying than ever. This practical book takes programmers (amateurs and pros alike) on a no-nonsense tour of ES6, along with some related tools and techniques. Author Ethan Brown (Web Development with Node and Express) not only guides you through simple and straightforward topics (variables, control flow, arrays), but also covers complex concepts such as functional and asynchronous programming. You’ll learn how to create powerful and responsive web applications on the client, or with Node.js on the server. Use ES6 today and transcompile code to portable ES5 Translate data into a format that JavaScript can use Understand the basic usage and mechanics of JavaScript functions Explore objects and object-oriented programming Tackle new concepts such as iterators, generators, and proxies Grasp the complexities of asynchronous programming Work with the Document Object Model for browser-based apps Learn Node.js fundamentals for developing server-side applications

JavaScript: The New Toys explores the newest features of the world's most popular programming language while also showing readers how to track what's coming next. After setting the stage by covering who manages the process of improving JavaScript, how new features get introduced, terminology, and a high-level overview of new features, it details each new or updated item in depth, with example uses, possible pitfalls, and expert recommendations for updating old habits in light of new features. JavaScript: The New Toys: Covers all the additions to JavaScript in ES2015-ES2020 plus a preview of what's coming next Explores the latest syntax: nullish coalescing, optional chaining, let and const, class syntax, private methods, private fields, new.target, numeric separators, BigInt, destructuring, default parameters, arrow functions, async functions, await, generator functions, ... (rest and spread), template literals, binary and octal literals, ** (exponentiation), computed property/method names, for-of, for-await-of, shorthand properties, and others Details the new features and patterns including modules, promises, iteration, generators, Symbol, Proxy, reflection, typed arrays, Atomics, shared memory, WeakMap, WeakSet, and more Highlights common pitfalls and explains how to avoid them Shows how to follow the improvements process and even participate in the process yourself Explains how to use new features even before they're widely supported With its comprehensive coverage and friendly, accessible style, JavaScript: The New Toys provides an invaluable resource for programmers everywhere, whether they work in web development, Node.js, Electron, Windows Universal Apps, or another JavaScript environment.

JavaScript is an easy-to-use, flexible, dynamic, prototype-based programming language predominantly used over the web. Although the initial focus of the language was to assist in the generation of dynamic web content, it soon found its way into numerous other applications. This book aims to cover the fundamentals of the language by providing a strong start for people who wish to start their journey to the JavaScript programming language. It provides the mandatory theoretical background, which is much needed for implementation of the exhaustive hands-on exercises and includes over 4000 lines of code for grasping a maximum understanding of the material. FEATURES A strong theoretical background and understanding of the fundamentals of the JavaScript language Hands-on and demo exercises at the end of every chapter Exercises, theory-based questions, MCQs and true/false questions for helping readers to evaluate their understanding from time to time A dedicated chapter providing extended case studies for using the language This book is targeted at undergraduate as well as postgraduate students who want to learn about front-end programming or who wish to learn a lightweight, easy-to-use programming language for working on their projects. For programmers having experience in other languages, it will serve as a quick summary to get a hold of a new language.
