JavaScript is a tool for the gurus who create highly useful applications, but it has some limitations. To overcome these limitations, a concept called JavaScript promises is rising rapidly in popularity. Promises makes writing complex logics more manageable and easy. This book starts with an introduction to JavaScript promises and how it has evolved over time. You will learn the JavaScript asynchronous model and how JavaScript handles asynchronous programming. Next, you will explore the promises paradigm and its advantages. Finally, this book will show you how to implement promises in platforms used in project development including WinRT, jQuery, and Node.js.

Asynchronous JavaScript is everywhere, whether you’re using Ajax, AngularJS, Node.js, or WebRTC. This practical guide shows intermediate to advanced JavaScript developers how Promises can help you manage asynchronous code effectively—including the inevitable flood of callbacks as your codebase grows. You’ll learn the inner workings of Promises and ways to avoid difficulties and missteps when using them. The ability to asynchronously fetch data and load scripts in the browser broadens the capabilities of JavaScript applications. But if you don’t understand how the async part works, you’ll wind up with unpredictable code that’s difficult to maintain. This book is ideal whether you’re new to Promises or want to expand your knowledge of this technology. Understand how async JavaScript works by delving into callbacks, the event loop, and threading Learn how Promises organize callbacks into discrete steps that are easier to read and maintain Examine scenarios you’ll encounter and techniques you can use when writing real-world applications Use features in the Bluebird library and jQuery to work with Promises Learn how the Promise API handles asynchronous errors Explore ECMAScript 6 language features that simplify Promise-related code
