Solution for Rosetta Code: Hash from two arrays

What is your hint or solution suggestion?

Object.fromEntries is from ES2019, which makes mapping array values to an object far easier. Only the index i is needed.

Solution 1
function arrToObj (keys, vals) {
  return Object.fromEntries(keys.map((_, i) => [keys[i], vals[i]]));
}
