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.
##总之JS是个难用的语言
评分 评分##如今,JS可以说是一统天下,前端毫无疑问,后端有了Node,移动端有了React。 JS这门语言由于是在10天内创建出来的,难免存在着一些不足点。 创始人Brendan Eich一开始打算用scheme来实现,无奈公司领导说,让这个新语言的语法像java,所以造就了现在JS中一些让大家误会的地方...
评分 评分##这本书在离开深圳之前送给了闭小姐,希望能在她手上继续发光发热。 这本书是写过一段时间的 js 之后,才能理解其中的金玉良言。就如同自己真正写过一段时间的 java 之后,才能真正理解 《effective java》 接触过多门编程语言,有时候会在想,编程语言之间的界限是什么?我们用...
评分 评分 评分##重新读了一遍。当年读的时候真的什么也不懂,只觉得这本书里的JS似乎更清晰。 重读的最大收获不是在于了解到一些好的习惯和坏语法特性的处理方案,而是在于发现:可以设计语言的子集来形成一种代码规范。 类型系统,代码规范的文档,代码评审的流程,都是规避错误的一种方法,...
