Who This Book Is For

This book is written for any JavaScript developer who wants to learn how to write more efficient, powerful, and maintainable applications that utilize the latest developments in JavaScript.

What You Will Learn

Understand exactly how JavaScript works in a web browser environment and how these mechanisms power our event-driven JavaScript code
Use promises to turn complex synchronization scenarios into readable and maintainable code
Compute values lazily and avoid unnecessary memory allocations using generators
Write concurrent code that doesn't feel like concurrent code by abstracting away boilerplate chores
Leverage true hardware parallelism with web workers to get better performance
Get to grips with the NodeJS model of concurrency and learn why it's good for I/O-intensive web applications

In Detail

JavaScript has evolved to adopt concurrent capabilities―one of the reasons why it is still at the forefront of modern web development. This book helps you dive into concurrent JavaScript and demonstrates how to apply its core principles, key techniques, and tools to a range of complex development challenges. Built around the three core principles of concurrency―parallelism, synchronization, and conservation―you will learn everything you need to unlock a more efficient and dynamic JavaScript in order to lay the foundations of even better user experiences.

Throughout the book you will learn how to put these principles into action by using a range of development approaches. Covering everything from JavaScript promises, web workers, and generators to functional programming techniques, everything you learn will have a real impact on the performance of your applications. You will also learn how to move between the client and server for a frictionless and fully realized approach to development. With further guidance on concurrent programming with NodeJS, JavaScript Concurrency is committed to making you a better web developer.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places.

We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
