商品描述

If you’re an advanced beginner or intermediate JavaScript developer, JavaScript Enlightenment will solidify your understanding of the language—especially if you use a JavaScript library. In this concise book, JavaScript expert Cody Lindley (jQuery Cookbook) provides an accurate view of the language by examining its objects and supporting nuances.

Libraries and frameworks help you build web applications quickly and efficiently, but when things go wrong or performance becomes an issue, knowing how and why they work is critical. If you’re ready to go under the hood and get your hands dirty with JavaScript internals, this is your book.

  • Get a short and digestible summary of ECMA-262, Edition 3, backed by real code you can run instantly
  • Examine the creation of JavaScript objects
  • Learn complex values, primitive values, scope, and inheritance
  • Understand the importance of the head object
  • Work with string, number, and Boolean objects and values
  • Discover how to use the null value and the built-in math object
  • Get into the details—beyond Mozilla’s reference guide for JavaScript 1.5

商品描述(中文翻譯)

如果你是一位進階初學者或中級 JavaScript 開發者，《JavaScript Enlightenment》將會加強你對這門語言的理解，尤其是如果你使用 JavaScript 函式庫的話。在這本簡明的書中，JavaScript 專家 Cody Lindley（《jQuery Cookbook》的作者）通過檢視語言的物件和相關細節，提供了一個準確的觀點。

函式庫和框架可以幫助你快速高效地構建網絡應用程式，但當出現問題或性能成為一個問題時，了解它們的工作原理和原因就變得至關重要。如果你準備深入研究 JavaScript 內部並親自動手，這本書就是為你而寫的。

本書提供了 ECMA-262 第 3 版的簡明摘要，並附有可以立即運行的真實代碼。你將學習 JavaScript 物件的創建、複雜值、原始值、作用域和繼承。你還將了解 head 物件的重要性，以及如何使用字串、數字和布林物件和值。此外，你還將發現如何使用 null 值和內建的數學物件。本書還深入探討了 Mozilla JavaScript 1.5 的參考指南之外的細節。
