Benchmark: Object.entries VS Object.values Perf

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 uniqNodes = new Set(); Object.entries(window.parentObj).forEach(([_identifier, node]) => { if (!uniqNodes.has(node)) { uniqNodes.add(node); } });
Object.values
const uniqNodes = new Set(); Object.values(window.parentObj).forEach((node) => { if (!uniqNodes.has(node)) { uniqNodes.add(node); } });
