/**
 * ## `Ec.itArray`
 *
 * ### 1. 基本介绍
 *
 * 迭代输入的数组，然后执行函数`executor`，该函数签名如下，它有两个参数：
 *
 * ```js
 * function(item, index){
 *
 * }
 * ```
 *
 * ### 2. 内置参数
 *
 * |参数|类型|含义|
 * |---|---|:---|
 * |item|`Object/<Any>`|每一个数组中的元素，任意类型。|
 * |index|Number|该元素在数组中的索引值。|
 *
 * @memberOf module:_epic
 * @param {Array} array 被迭代的数组
 * @param {Function} executor 第二参数，必须是一个标准的JavaScript函数
 * @returns {Array} 返回执行完成后的数组
