You work in a loop: write code, get feedback, iterate. The faster you get feedback, the faster you can learn and become a more effective developer. Test-Driven React helps you refine your React workflow to give you the feedback you need as quickly as possible. Write strong tests and run them continuously as you work, split complex code up into manageable pieces, and stay focused on what's important by automating away mundane, trivial tasks. Adopt these techniques and you'll be able to avoid productivity traps and start building React components at a stunning pace! React has revolutionized web development by abstracting away the details of DOM manipulation. That conceptual elegance has opened the door to a new generation of web testing: clear, expressive, and lightning-fast. That makes React a perfect fit for test-driven development (TDD), a methodology in which tests are a blueprint instead of an afterthought. Each chapter will present new projects to challenge you and new tools to help you. Write fast, portable tests with Jest. Keep your code tidy with ESLint and Prettier. Perform every task you need from a single window with VS Code. See your test output directly in your code with Wallaby. Use the JavaScript features of the future with Babel. Make assertions about React component behavior with Enzyme. And style components in a testable way with styled-components. By understanding every piece of your project's stack, you'll feel more confident and able to focus on what matters: writing reliable and maintainable code. Discover a more joyful React development experience. Let your tests lead the way! What You Need: You'll need a working knowledge of JavaScript and a computer running macOS, Windows, or Linux.

For 15 years, dynamic web content has been written in a single language: JavaScript. Now, for the first time, programmers have an alternative that doesn't add an extra layer of abstraction or require plugins. CoffeeScript provides all of JavaScript's functionality wrapped in a cleaner, more succinct syntax that encourages use of "the good parts" of the language. CoffeeScript: Accelerated JavaScript Development is aimed at programmers who want to get a grip on this new language while improving their understanding of JavaScript. You'll learn about time-saving features like list comprehensions and splats, organize your code into modules with extensible classes, and get your feet wet with jQuery by building a fast-paced word game. The book also introduces Node.js, the foremost server-side JavaScript environment. Node and CoffeeScript turn out to be a great match, allowing you to develop the front and back ends of a web application in the same language. With CoffeeScript in your toolkit, you can write great code anywhere.

CoffeeScript: Accelerated JavaScript Development

With the advent of HTML5, front-end MVC, and Node.js, JavaScript is ubiquitous--and still messy. This book will give you a solid foundation for managing async tasks without losing your sanity in a tangle of callbacks. It's a fast-paced guide to the most essential techniques for dealing with async behavior, including PubSub, evented models, and Promises. With these tricks up your sleeve, you'll be better prepared to manage the complexity of large web apps and deliver responsive code. With Async JavaScript, you'll develop a deeper understanding of the JavaScript language. You'll start with a ground-up primer on the JavaScript event model--key to avoiding many of the most common mistakes JavaScripters make. From there you'll see tools and design patterns for turning that conceptual understanding into practical code. The concepts in the book are illustrated with runnable examples drawn from both the browser and the Node.js server framework, incorporating complementary libraries including jQuery, Backbone.js, and Async.js. You'll learn how to create dynamic web pages and highly concurrent servers by mastering the art of distributing events to where they need to be handled, rather than nesting callbacks within callbacks within callbacks. Async JavaScript will get you up and running with real web development quickly. By the time you've finished the Promises chapter, you'll be parallelizing Ajax requests or running animations in sequence. By the end of the book, you'll even know how to leverage Web Workers and AMD for JavaScript applications with cutting-edge performance. Most importantly, you'll have the knowledge you need to write async code with confidence. What You Need: Basic knowledge of JavaScript is recommended. If you feel that you're not up to speed, see the "Resources for Learning JavaScript" section in the preface.

Over the last five years, CoffeeScript has taken the web development world by storm. With the humble motto "It's just JavaScript," CoffeeScript provides all the power of the JavaScript language in a friendly and elegant package. This extensively revised and updated new edition includes an all-new project to demonstrate CoffeeScript in action, both in the browser and on a Node.js server. There's no faster way to learn to write a modern web application. This new edition has been extensively revised and updated to reflect the current state and features of CoffeeScript. Every chapter has been revised and refactored, and new sections and a new chapter on testing have been added. If you already know JavaScript, this book will make your transition to CoffeeScript easy. If you're new to JavaScript, it's a great place to start. New in this edition: Automating setup with the Grunt task runner Using CoffeeScript classes with the Backbone framework Using CoffeeScript's simple callback syntax to interact with the Express framework A new chapter on client-side and server-side testing with Intern * A new project that gives you hands-on experience with browser-side and server-side CoffeeScript CoffeeScript is every bit as portable and effective as JavaScript. It aids development by adding a bevy of features, such as classes, splats, list comprehensions, and destructuring. These features make it easier to write clear, readable code, and by learning how these features work, you'll deepen your understand of JavaScript as well. This book is your complete guide to writing better JavaScript code, faster.
