Array.length与Array.prototype.length
问题描述：
我发现Array对象和Array.prototype都具有length属性.我对使用Array.length属性感到困惑.您如何使用它?
I found that both the Array Object and Array.prototype have the length property. I am confused on using the Array.length property. How do you use it?
Console.log(Object.getOwnpropertyNames(Array));//As per Internet Explorer
输出:
length,arguments,caller,prototype,isArray,
Prototype和isArray可用，但是如何使用length属性?
Prototype and isArray is usable but how do you use the length property?
答
Array是构造函数.
所有函数都有一个length属性，该属性返回函数定义中已声明参数的数量.
All functions have a length property that returns the number of declared parameters in the function definition.
