In Detail

Promises are a new programming paradigm in JavaScript that allow developers to request data that they don't have yet and deal with it at a non-determined point in the future (asynchronously). Starting with the basics of the promise objects, we'll be able to leverage the maximum capabilities of promises when writing applications.

This book starts by giving you some background information on the asynchronous programming model in JavaScript, recognizing its importance in JavaScript programming. It then walks you through the key concepts and intricacies of the Promises API. Following that, you will learn how you can write complex asynchronous operations with chained promises and be able to catch and handle exceptions. With this book, you'll learn how to write better asynchronous operations using JavaScript promises.
