What have you tried so far? Where are you stuck? How would you define "best"? — Nico Haase, Aug 25 '22 at 09:38

This is an easy way to do it only if your array structure looks like what you provided though. Is it the best way? Who am I to judge.

const array = ['RUNNING WATTS', '12,500', 'PEAK AMPS @ 120V', '125.00', 'RUNNING AMPS @ 120V', '100.00'];
let result = {}
result[array[0]] = array[1]
result[array[2]] = array[3]
result[array[4]] = array[5]
console.log(result);

You could use a simple reduce method which would work with an even bigger array:


const arr = ['RUNNING WATTS', '12,500', 'PEAK AMPS @ 120V', '125.00', 'RUNNING AMPS @ 120V', '100.00'];
arr.reduce((acc, val, idx, ref) => {
  if (idx % 2 == 0) {
    acc[val] = ref[idx + 1]
  }
  return acc
}, {})
