Benchmark: Lodash difference vs Set & Filter vs Map

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var arr1 = [];
for(let i = 0; i < 100000; i++) {
  arr1.push({"index": i});
}

var arr2 = [];
for(let i = 49000; i >= 0; i--) {
  arr2.push(arr1[i*2]);
}

Tests:

Lodash
const notInArr = _.difference(arr2, arr1)
Set & Filter
const arr2Set = new Set(arr2); const notInArr2 = arr1.filter(value => !arr2Set.has(value));
map
const arr2Map = new Map(arr2.map((e2) => ([e2.index, e2]))); const notInArr2 = arr1.filter(value => !arr2Map.has(value));
