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 compact guide explores JavaScript types in greater depth than previous treatments, defining the problems of coercion, demonstrating why types work, and showing developers how to take advantage of those features.
The type system in JavaScript is subject to several misconceptions. Many developers believe that JavaScript has no types, but that's not the case. JavaScript uses a number of types behind the scenes, and has a sophisticated system of implicit and explicit coercion between the various types. This book gives you the complete story.
Like other books in this series, You Don’t Know JS: Types & Grammar dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can achieve true JavaScript mastery.
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，這本簡明的指南比以往的處理更深入地探討了 JavaScript 的類型，定義了強制轉換的問題，展示了類型為何有效，並向開發者展示如何利用這些特性。
JavaScript 的類型系統存在幾個誤解。許多開發者認為 JavaScript 沒有類型，但事實並非如此。JavaScript 在背後使用了多種類型，並且在各種類型之間有一個複雜的隱式和顯式強制轉換系統。本書將為你提供完整的故事。
與本系列的其他書籍類似，《You Don’t Know JS: Types & Grammar》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，你可以實現真正的 JavaScript 精通。
