Benchmark: Intersection filter vs lodash intersection test unsorted array

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 = [7, 2, 4, 1, 9, 8, 6, 3, 5]
var arr2 = [3, 4, 1, 2];

Tests:

filter unsorted
const result = arr1.filter(el => arr2.includes(el))
lodash intersection unsort
const result = _.intersection(arr1, arr2)
filter sorted
const sortedArr1 = arr1.sort() const sortedArr2 = arr2.sort() const result = sortedArr1.filter(el => sortedArr2.includes(el))
lodash intersection sorted
const sortedArr1 = arr1.sort() const sortedArr2 = arr2.sort() const result = _.intersection(sortedArr1, sortedArr2)
