Multithreaded JavaScript - by Thomas Hunter & Bryan English (Paperback)

About the Book

"With this practical book, intermediate JavaScript developers will come to understand the strengths and weaknesses of web worker APIs provided in browsers and the worker threads module provided by Node.js. Authors Thomas Hunter II and Bryan English focus on two approaches to buildings multithreaded applications: one using message passing and the other using shared memory. You'll learn APIs for implementing each, including when you might want to use one approach or the other, and when you can combine them"--

Book Synopsis

Traditionally, JavaScript has been a single-threaded language. Nearly all online forum posts, books, online documentation, and libraries refer to the language as single threaded. Thanks to recent advancements in the language--such as the Atomics and SharedArrayBuffers objects and Web Workers in the browser--JavaScript is now a multi-threaded language. These features will go down as being the biggest paradigm shift for the world's most popular programming language.

Multithreaded JavaScript explores the various features that JavaScript runtimes have at their disposal for implementing multithreaded programming, providing both practical real-world examples, as well as reference material.

• Learn what multithreaded programming is and how you can benefit from it
• Understand the differences between a web worker, a service worker, and a worker thread
• Know when and when not to use threads in an application
• Orchestrate communication between threads by leveraging the Atomics object
• Build high-performance applications using the knowledge you gain from this book
• Benchmark performance to learn if you'll benefit from multithreading
