从N到最后一个元素的切片数组 [英] slice array from N to last element

问题描述

如何进行这种转换?

["a","b","c","d","e"] // => ["c", "d", "e"]

我当时以为 slice 可以做到这一点，但是..

I was thinking that slice can do this, but..

["a","b","c","d","e"].slice(2,-1) // [ 'c', 'd' ]
["a","b","c","d","e"].slice(2,0)  // []

推荐答案

不要使用第二个参数:

Array.slice(2);

如果省略end，则slice提取到序列的末尾.

If end is omitted, slice extracts to the end of the sequence.
