函数式编程是一种强调和使智能化代码编写的风格,可以最大程度地减少复杂性并增加模块化。这是一种通过巧妙地改变、组合和使用函数来编写更清洁的代码的方式。JavaScript 为这种方法提供了一个极好的媒介。互联网的脚本语言 JavaScript 实际上是一种本质上的函数式语言。通过学习如何暴露它作为函数式语言的真实身份,我们...
Object Methods 迄今为止,我们讨论除了Objects外的所有type的方法,之所以这么安排是因为: 1.我希望保持所有object-related资料在一个集中的地方; 2.大多数你可以使用的methods就是你自己创建的那些方法 然而,对于object对象本身也有一些built-in的方法。既然你创建的任何对象都是一个Object(即:从Object.prototype来继承的...

All string methods return a new string. They don't modify the original string. Formally said: Strings are immutable: Strings cannot be changed, only replaced. Thetrim()method removes whitespace from both sides of a string: Example lettext1 =" Hello World! "; ...
using a reference to the object, call its functions to operate over the data (known asmethods). 使用对对象的引用,调用其函数对数据进行操作(称为方法)。 Many languages extend the concept with things like “properties” (fields that are methods actually, aka getters/setters), “events” (fields...
