Array.length 长度为1 Array.name 名称为"Array" Array.prototype 指向Arrayt构造函数的原型,可以为所有 Array 类型的对象添加属性。 3.2 Array构造函数的方法 Array.from() 从一个类似数组或可迭代对象中创建一个新的数组实例。(ES6新增方法,会在ES6专题中进行详细讲解) 语法: 代码语言:javascript 代码运行次数:0...

4、from() 方法:将拥有 length 属性的对象或可迭代的对象,返回为一个新的数组。 用法:Array.from(object,[mapFunction],[thisValue]) object(必需):要转换为数组的对象 mapFunction(可选):数组中每个元素要调用的函数 thisValue(可选):映射函数(mapFunction)中的 this 对象 vararr = [1,2,3,4,5];vara...

There’s no universal way of calculating the size of C-style arrays without worrying about many edge cases, and that’s why thestd::vectorclass exists. Usearray.size()Function to Calculate Array Length in C++ In C++, thearray.size()functionallows us to determine the size of an array at...
var a = [] a['11'] = 23 // 11会被当成索引,不会存储为key a.length // 12 注意:如果数组的索引是能够被转为数字的话,它会被当成数字索引。 类数组 一组通过数字索引的值(如 arguments,DOM 元素列表...) 类数组转换为数组(slice) function demo() { var args = arguments var arr = Array....
