Combining two arrays into one object in javascript

Question

I want to combine two arrays into one Object with name "data" Didn't find any efficient way

arrays:

var N =[ 1, 2, 3];
var s =[ a, b, c];

combine them into object:

var data= { s:[ a, b, c], N: [ 1, 2, 3 ] };

var data = {s: s, N: N};! Or in recent ECMAScripts: var data = {s, N};! — ibrahim mahrir

The easiest way would be:

const N = [1, 2, 3];
const s = ['a', 'b', 'c'];
const data = { s, N };

This is equivalent to:

const N =[ 1, 2, 3];
const s = ['a', 'b', 'c'];
const data = { s: s, N: N };

Note: I used const since the variables aren't reassigned.

Do it this way:

var N =[ 1, 2, 3];
var s =[ a, b, c];

var obj = {N, s};

Just pass your arrays (N and s) as variables to your new object. You can do this in few ways:

let myObject = { N: N, s: s } If you do this way you can type any other key. For example: let myObject = { firstArray: N, secondArray: s } and now you can access to N and s arrays as myObject.firstArray etc
Use short notation: let myObject = { N, s } This code will look up for variables N and s and write it inside your new object, which will give the same result as let myObject = { N: N, s: s }
