`Array.of()` 方法创建一个具有可变数量参数的新数组实例，而不考虑参数的数量或类型。

`Array.of()` 和 `Array` 构造函数之间的区别在于处理整数参数：`Array.of(7)` 创建一个具有单个元素 7 的数组，而 `Array(7)` 创建一个长度为7的空数组（注意：这是指一个有7个空位(empty)的数组，而不是由7个`undefined`组成的数组）。

    Array.of(7);       // [7]
    Array.of(1, 2, 3); // [1, 2, 3]

    Array(7);          // [ , , , , , , ]
    Array(1, 2, 3);    // [1, 2, 3]

## 语法

    Array.of(element0[, element1[, ...[, elementN]]])

### 参数

elementN
  任意个参数，将按顺序成为返回数组中的元素。

### 返回值

新的 `Array` 实例。

## 描述

此函数是ECMAScript 2015标准的一部分。详见 `Array.of 和` `Array.from` proposal 和 `Array.of` polyfill。

## 示例

    Array.of(1);         // [1]
    Array.of(1, 2, 3);   // [1, 2, 3]
    Array.of(undefined); // [undefined]

## 兼容旧环境

如果原生不支持的话，在其他代码之前执行以下代码会创建 `Array.of()` 。

    if (!Array.of) {
      Array.of = function() {
        return Array.prototype.slice.call(arguments);
      };
    }
