Method和Function不是JavaScript中独有的概念。Method是OOP编程模式中的概念：通常以一个类模拟一个对象。...
如此,这些因素就构成了函数成为 JavaScript 中的”一等公民“ // 作为变量保存变量、数组、对象varfuncA=function(){}// 作为变量varfuncB=[function(){}]// 作为数组变量varfuncC={method:function(){}}// 作为对象方法// 函数也是对象,意味着可以拥有属性varfuncD=function(){}funcD.name='funcD'// 赋值...
If a function is not a method of a JavaScript object, it is a function of the global object (see previous chapter). The example below creates an object with 3 properties, firstName, lastName, fullName. Example constperson = { firstName:"John", ...
Building up objects with methods is pretty much the same. Using the function operator to directly assign the method to the object means not having to go looking for the implementation. If you’re worried about performance, use theobject prototypeto declare the method only once for all the obje...
Since JavaScriptarraysdo not have a max() method, you can apply theMath.max()method instead. Example Math.max.apply(null, [1,2,3]);// Will also return 3 Try it Yourself » The first argument (null) does not matter. It is not used in this example. ...

Function 实例的 bind() 方法创建一个新函数,当调用该新函数时,它会调用原始函数并将其 this 关键字设置为给定的值,同时,还可以传入一系列指定的参数,这些参数会插入到调用新函数时传入的参数的前面。
