具體描述

Douglas Crockford is a Senior JavaScript Architect at Yahoo!. He is the maintainer of the JSON format, and a regular speaker at conferences on advanced JavaScript topic. He is also on the JavaScript 2.0 committee at ECMA.

Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book offers a detailed explanation of the features that make JavaScript an outstanding object-oriented programming language, and warns you about the bad parts.

In the process, JavaScript: The Good Parts defines a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole. Author Douglas Crockford, a member of JavaScript 2.0 committee at ECMA, is considered by many people in the development community to be the JavaScript expert.

A beautiful, elegant, lightweight and highly expressive language lies buried under a steaming pile of good intentions and blunders, he explains. The very good ideas include functions, loose typing, dynamic objects, and an expressive object literal notation. Awful ideas include a programming model based on global variables. With JavaScript: The Good Parts, you can release this elegant programming language from its old shell, and create more maintainable, extensible, and efficient code.

The book's topics include:

* Syntax

* Objects

* Functions

* Inheritance

* Arrays

* Regular expressions

* Methods

* Style

* Beautiful features

Appendices summarize JavaScript's bad parts and awful parts. But the greatest benefit of studying the good parts is that you can avoid the need to unlearn the bad parts. If you want to learn more about the bad parts and how to use them badly, consult any other JavaScript book.

JavaScript is the language of the Web -- the only language found in all browsers -- so avoiding it altogether is not an alternative. But, whether you're managing object libraries or just trying to get Ajax to run fast, Crockford's guidance in JavaScript: The Good Parts will help you create truly effective JavaScript code.

##乾活滿滿,是JS進階的一本好書。美中不足的是太老瞭,希望能再版。 以前讀過一次,這兩天又讀瞭一次,感受有所不同,趕緊記錄下來: 我的讀書筆記

##重新讀瞭一遍。當年讀的時候真的什麼也不懂,隻覺得這本書裏的JS似乎更清晰。 重讀的最大收獲不是在於瞭解到一些好的習慣和壞語法特性的處理方案,而是在於發現:可以設計語言的子集來形成一種代碼規範。 類型係統,代碼規範的文檔,代碼評審的流程,都是規避錯誤的一種方法,...

##作者寫得很有調調,這門語言就像是他自己的一件作品一樣。字裏行間透著自信,因為對語言太瞭解瞭,編程語言書籍典範之一種。Functions一章最有料,也最喜歡。

##if you want to read this book, you can almost skip the first two chapters, the first chapter is about why good parts, why JS is a great language. chapter 2 is merely a language syntax reference, i think this is totally against what the author indicated earl...
