"The nature of JavaScript is to be single threaded. This is reflected not only in libraries and applications, but also in online forum posts, books, and online documentation. Thanks to recent advancements in the platform--such as with web workers in the browser, worker_threads in Node.js, and the Atomics and SharedArrayBuffer objects--JavaScript engineers are able to build multi-threaded applications. 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, using a spectrum of API reference material and high level programming patterns. Learn what multithreaded programming is and how you can benefit from it Understand the differences between a dedicated worker, a shared worker, and a service worker Identify when and when not to use threads in an application Orchestrate communication between threads by leveraging the Atomics object Understand both the gains and pitfalls of using shared memory Benchmark performance to learn when you'll benefit from multiple threads" -- Amazon.com 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.

Learn what multithreaded programming is and how you can benefit from it; understand the differences between a dedicated worker, a shared worker, and a service worker; identify when and when not to use threads in an application; orchestrate communication between threads by leveraging the Atomics object; understand both the gains and pitfalls of using shared memory; and benchmark performance to learn when you'll benefit from multiple threads. --From publisher description Thanks to language advancements such as web workers in the browser, JavaScript is now a multithreaded language. What does that mean for you? In this practical book, authors Thomas Hunter II and Bryan English explain JavaScript threads as a programming concept and tool.
