Benchmark: Object entries, values, keys, and Array.from

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.obj = {};

for (let i = 0; i < 100; i++) {
	window.obj[makeid()] = makeid();
}

Tests:

entries
const len = Object.entries(window.obj).length;
Values
const len = Object.values(window.obj).length;
Keys
const len = Object.keys(window.obj).length;
Array.from
const len = Array.from(window.obj).length;
