Benchmark: map vs obj3 - MeasureThat.net

HTML Preparation code:

<script src="lodash.js"></script>

Script Preparation code:

var array = [...Array(1000).keys()];
var map = new Map(array.map(a =>[a,a]));
var obj = Object.fromEntries(map);
var setMap = new Map()
var setObj = {}

Tests:

getMap
for (let i = 0; i< 1000; i++ ){ map.get(i) }
getObj
for (let i = 0; i< 1000; i++ ){ obj[i] }
setMap
for (let i = 0; i< 1000; i++ ){ setMap.set(i,i) }
setObj
for (let i = 0; i< 1000; i++ ){ setObj[i] = i }
setMap2
for (let i = 0; i< 1000; i++ ){ map.set(i,i * 2) }
setObj2
for (let i = 0; i< 1000; i++ ){ obj[i] = i * 2 }
