Benchmark: Lodash: difference vs intersection1

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/lodash/4.16.0/lodash.min.js"></script>

Script Preparation code:

 var arrFull = new Array(20000);
    var arrOne = new Array(20000);
    var c = [];
    for(var x = 0; x < 20001; x++) {
        arrFull.push(x);
        arrOne.push(x);
    }

Tests:

Difference - Full
_.difference(arrFull, arrFull)
Intersection - Full
_.intersection(arrFull, arrFull)
Difference - Partial
_.difference(arrFull, arrOne)
Intersection - Partial
_.intersection(arrOne, arrFull)
filter1
c = arrOne.filter(x => arrFull.includes(x));
filter2
c = arrOne.filter(value => -1 !== arrFull.indexOf(value))
