Benchmark: object-iteration

Tests:

for in
var obj = { x: 1, y: 1, z: 1 } var total = 0 for (var prop in obj) { if (obj.hasOwnProperty(prop)) { total += obj[prop] } }
Object.keys functional
var obj = { x: 1, y: 1, z: 1 } var total = Object.keys(obj).reduce(function (acc, key) { return acc + obj[key] }, 0)
Object.keys functional with arrow
var obj = { x: 1, y: 1, z: 1 } var total = Object.keys(obj).reduce((acc, key) => { return acc + obj[key] }, 0)
Object.keys with for loop
var obj = { x: 1, y: 1, z: 1 } var keys = Object.keys(obj) var total = 0 for (var i = 0; i < keys.length; i++) { total += obj[keys[i]] }
Object.values functional
var obj = { x: 1, y: 1, z: 1 } var total = Object.values(obj).reduce(function (acc, val) { return acc + val }, 0)
Object.values functional with arrow
var obj = { x: 1, y: 1, z: 1 } var total = Object.values(obj).reduce((acc, val) => { return acc + val }, 0)
Object.values with for loop
var obj = { x: 1, y: 1, z: 1 } var vals = Object.values(obj) var total = 0 for (var i = 0; i < vals.length; i++) { total += vals[i] } })
