商品描述
No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. As part of the "You Don’t Know JS" series, this concise yet in-depth guide focuses on new asynchronous features and performance techniques—including Promises, generators, and Web Workers—that let you create sophisticated single-page web applications and escape callback hell in the process.
Like other books in this series, You Don’t Know JS: Async & Performance dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can become a true JavaScript master.
With this book you will:
- Explore old and new JavaScript methods for handling asynchronous programming
- Understand how callbacks let third parties control your program’s execution
- Address the "inversion of control" issue with JavaScript Promises
- Use generators to express async flow in a sequential, synchronous-looking fashion
- Tackle program-level performance with Web Workers, SIMD, and asm.js
- Learn valuable resources and techniques for benchmarking and tuning your expressions and statements
商品描述(中文翻譯)
無論你對 JavaScript 有多少經驗,可能都不完全理解這門語言。作為「You Don’t Know JS」系列的一部分,這本簡明而深入的指南專注於新的非同步特性和性能技術,包括 Promises、生成器(generators)和 Web Workers,這些技術讓你能夠創建複雜的單頁網頁應用程式,並在此過程中擺脫回呼地獄(callback hell)。
與本系列的其他書籍類似,《You Don’t Know JS: Async & Performance》深入探討了許多 JavaScript 程式設計師簡單避開的語言中較棘手的部分。掌握這些知識後,你可以成為真正的 JavaScript 大師。
透過這本書,你將會:
- 探索舊的和新的 JavaScript 方法來處理非同步程式設計
- 理解回呼(callbacks)如何讓第三方控制你的程式執行
- 解決 JavaScript Promises 的「控制反轉」(inversion of control)問題
- 使用生成器以順序、同步的方式表達非同步流程
- 利用 Web Workers、SIMD 和 asm.js 解決程式層級的性能問題
- 學習有價值的資源和技術來基準測試和調整你的表達式和語句
