Benchmark: eq vs object.keys vs object.values for objects

Script Preparation code:

var obj = {
  'a': {
    id: 'a',
    num: 1
  },
  'b': {
    id: 'b',
    num: 1
  },
  'c': {
    id: 'c',
    num: 1
  },
  'd': {
    id: 'd',
    num: 1
  },
  'e': {
    id: 'e',
    num: 1
  },
  'f': {
    id: 'f',
    num: 1
  },
  'g': {
    id: 'g',
    num: 1
  },
};

var arr = [
  {
    id: 'a',
    num: 1
  },
  {
    id: 'b',
    num: 1
  },
  {
    id: 'c',
    num: 1
  },
  {
    id: 'd',
    num: 1
  },
  {
    id: 'e',
    num: 1
  },
  {
    id: 'f',
    num: 1
  },
  {
    id: 'g',
    num: 1
  },
];

Tests:

for-in
for (var i=10000; i > 0; i--) { arr.forEach(i => { console.log(i.id === 'e') }) }
Object.keys
for (var i=10000; i > 0; i--) { Object.keys(obj).forEach(key => console.log(obj[key].id)); }
Object.values
for (var i=10000; i > 0; i--) { Object.values(obj).forEach(n => console.log(n.id)); }
