A simple loop does just fine.

let person = {}

let keys = ['name', 'age', 'work']; let values = ['Adam', 23, 'none'];

for (const i of Array(keys.length).keys()) {
  const key = keys[i];
  const val = values[i];
  person[key] = val;
}

console.log(person);

That's a very roundabout way to loop over the indices... – jonrsharpe Apr 12 '22 at 21:39
@jonrsharpe ye – async await Apr 12 '22 at 21:40
For which read: bad. – jonrsharpe Apr 12 '22 at 21:40
@jonrsharpe why? Trying out some stuff I read on [this post](https://stackoverflow.com/questions/8273047/javascript-function-similar-to-python-range) – async await Apr 12 '22 at 21:41
It's because the code obscures the nature of the loop. `for (let i = 0; i < keys.length; i++) {...}` is more readable. Also that post is from 2011. – Andy Apr 12 '22 at 21:58

@Andy good input, I'll keep that in mind – async await Apr 12 '22 at 21:59
