const array = [1,2,3];array.push(4);//[1,2,3,4]array.push(5,6,7);//[1,2,3,4,5,6,7] 2. pop - 用于删除数组的最后一个元素并返回被删除的元素。 const array = [1,2,3,4];const value= array.pop();//array [1,2,3] value 4 3. shift - 用于删除数组的第一个元素并返...
我们可以利用对arguments对象(array-like object,需要转换成真正的 array)进行shift来取出,像这个方法,主要利用它们来分出作为作用域的object,然后巧妙地把余下的参数数组传给fn,即调用我们想限定到object作用域内的函数。 二、使用pop 最近在试用 seajs,我们就拿它的一个 api 来说吧: 1define(id, dependencies, ...
（1）shift方法shifit方法将移除最前一个元素并返回该元素值，数组中元素自动前移语法：array.shift()举个🍐 使用shift删除arr第一个元素（2）pop方法pop（）方法用于删除数组的最后一个元素并返回删除的元素语法：array.pop()(3)splice方法splice方法将删除从指定位置deletePos(删除开始的位置)开始的指定数量delete...

The partition() method is similar to an eager version of filter(), but it returns two collections; the first contains the items that would have been discarded by filter(), and the second contains the items that would have been kept. It always returns an array of exactly two collections, ...
