Benchmark: Reading object values in loop: Object.keys vs Object.values

Script Preparation code:

var obj = {};

for (let i = 0; i < 1000; i++) {
  obj['abc_' + i] = i;
}

Tests:

Object.keys
const keys = Object.keys(obj); keys.forEach(function(key, value) { console.log(obj[key]); });
Object.values
const values = Object.values(obj); values.forEach(function(key, value) { console.log(value); });
