Benchmark: Lodash Intersection with Arrays vs. native with sets vs. native filter with arrays

Script Preparation code:

var arr1 = [];
for (let i = 0; i < 1000; i++) {
  arr1.push(i);
}
arr1 = _.shuffle(arr1);

var arr2 = [];
for (let i = 500; i < 1500; i++) {
  arr2.push(i);
}
arr2 = _.shuffle(arr2);
set1 = new Set(arr1);

Tests:

native arrays
arr1.filter(item => arr2.indexOf(item) > -1);
lodash intersection
_.intersection(arr1, arr2);
native with sets
arr2.filter(item => set1.has(item));
