商品描述

Until recently, JavaScript concurrency was achieved by splitting up tasks and scheduling them. But 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.

Not every problem needs to be solved with threads, but having this tool in your toolbox will help you arrive at the most appropriate solution. This book explores various features that JavaScript runtimes have at their disposal for implementing multithreaded programs. By exploring practical real-world examples, you'll discover when to use threads and when not to.

  • 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

商品描述(中文翻譯)

直到最近，JavaScript 的併發是透過將任務拆分並進行排程來實現的。但多虧了語言的進步，例如瀏覽器中的 web workers，JavaScript 現在成為了一種多執行緒語言。這對你意味著什麼？在這本實用的書中，作者 Thomas Hunter II 和 Bryan English 解釋了 JavaScript 執行緒作為一種程式設計概念和工具。

並不是每個問題都需要用執行緒來解決，但擁有這個工具在你的工具箱中將幫助你找到最合適的解決方案。本書探討了 JavaScript 執行環境可用於實現多執行緒程式的各種特性。透過探索實際的真實世界範例，你將發現何時應該使用執行緒，何時不應該使用。

- 了解什麼是多執行緒程式設計以及你如何從中受益
- 理解 web worker、service worker 和 worker thread 之間的差異
- 知道在應用程式中何時應該使用執行緒，何時不應該使用
- 利用 Atomics 物件協調執行緒之間的通信
- 使用你從本書中獲得的知識構建高效能應用程式
- 基準測試性能以了解你是否會從多執行緒中受益
