Convert array of object values from int to string

Question

I have the following array

 [ { "id": 1, "name": "Test" }, { "id": 2, "name": "Test2" }

How can I convert that to

 [ { "id": '1', "name": "Test" }, { "id": '2', "name": "Test2" }

using javascript - what have you tried?, perhaps "toString" is a start — Bravo, Nov 06 '18 at 11:23
Please, show what have you tried so far, then provide a [MCVE : Minimal, Complete, and Verifiable Example](http://stackoverflow.com/help/mcve). If people around can easily read and understand what you mean, or what the problem is, they'll be more likely willing to help :) — Dwhitz, Nov 06 '18 at 11:25

For all the objects in an array, you want to convert a property type from number to string. You can use Array.forEach to achieve the same.

let arr = [ { "id": 1, "name": "Test" }, { "id": 2, "name": "Test2" }];
arr.forEach(v => v.id += '');
console.log(arr);

You can use toString method like ``arr.forEach(v => v.id.toString());`` It will be better performance wise. – Imran Qamer Nov 06 '18 at 11:32
@ImranQamer - Using `toString` is fine and is a possible alternate, but I feel that you will need to assign the value back to `v.id` as well. – Nikhil Aggarwal Nov 06 '18 at 11:33
Yes, You are right i missed that part, i edited my comment. – Imran Qamer Nov 06 '18 at 11:44
it should be ``arr.forEach(v => v.id=v.id.toString());`` – Imran Qamer Nov 06 '18 at 11:44
