怎么将两个一维数组合并成一个二维数组在JavaScript中？

Question

比如这样:

var array1 = ["one","two","three'];
var array2 = ["1","2","3"];

怎么将这两个数组(假定两个数组长度相等)合并成
var array = [["one","1"],["two","2"],["three","3"]]?
有办法实现吗？新手求助!

Answer 1

自行合并咯，想怎么合都行

array1.map((item, idx) => [item, array2[idx]]);

Answer 2

Array.from还可以接受第二个参数，作用类似于数组的map方法，用来对每个元素进行处理，将处理后的值放入返回的数组。

Array.from(array1, (item, idx) => [item, array2[idx]])

Answer 3

看到楼上的，突然想到类似的操作

var array1 = ["one","two","three"];
var array2 = ["1","2","3"];
var arr=[];
array1.forEach((currentValue,index)=>arr.push([currentValue,array2[index]]));
传统一点：
var array1 = ["one","two","three"];
var array2 = ["1","2","3"];
var arrayAll=[];
for(let i=0;i<array1.length;i++){
arrayAll.push([array1[i],array2[i]])
}

Answer 4

[].concat.apply([],arr);
