Use defined variable in array

Question

Confusing but hopefully someone knows how to do this

I have this code:

const abc = [];
const value = "bar";
const setting = "foo";
abc.setting = value;
console.log(abc);

I want it to output [ foo: 'bar' ] but it outputs [ setting: 'bar' ]

[ setting: 'bar' ] is an invalid type. do you mean { setting: 'bar' }? — wangdev87, Dec 31 '20 at 01:42

Use [] to indicate the dynamic keys for object.

const abc = [];
const newObj = {};
const value = "bar";
const setting = "foo";
newObj[setting] = value;
abc.push(newObj);
console.log(abc);
