Script Preparation code:

function makeid() {
  var text = "";
  var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

  for (var i = 0; i < 5; i++)
    text += possible.charAt(Math.floor(Math.random() * possible.length));

  return text;
}

window.parentObj = {};

for (let i = 0; i < 100; i++) {
	window.parentObj[makeid()] = makeid();
}

Tests:

Object.entries
const newObj = {}; Object.entries(window.parentObj).map(([k, v]) => { newObj[k] = v; });
Object.values
const newObj = {}; Object.values(window.parentObj).map((o, i) => { newObj[newObj[i]] = o; });
Object.keys
const newObj = {}; Object.keys(window.parentObj).map((k, i) => { newObj[k] = window.parentObj[k]; });
Object.values with forEach
const newObj = {}; Object.values(window.parentObj).forEach((o, i) => { newObj[newObj[i]] = o; });
