在JS中将2个数组添加到新数组

Question

I'm having difficulty adding arrays into another array without it merging all of the items inside of the array together. I've tried push and concat and they don't seem to do what I'm looking for.

var a = [1,2,3]

var b = [4,5,6]

result = [[1,2,3],[4,5,6]]

Answer 1

Define your new array based on your current variables like this:

var a = [1,2,3];
var b = [4,5,6];

var result = [a,b]; //Creates [[1,2,3],[4,5,6]]

Answer 2

Can't you simply add to an another array?

Ie var result = []; result.push(a); result.push(b); var result = []; result.push(a); result.push(b);

Or just declare it as such:

 result = [a,b]

Answer 3

This should do the trick:

var a = [1,2,3]

var b = ["a","b","c"]

result = [a,b] // [[1,2,3],["a","b","c"]] 

With Fiddle .

Answer 4

use this way:

  var a = [1,2,3];
    var b = ['a','b','c'];
    var c =[];
    c.push(a);
    c.push(b);
    console.log(c);
