Benchmark: Array filter vs Set delete

Script Preparation code:

function arrayWithLength(length) {
    return Array(length).fill().map((_, i) => i);
}
var arr10 = arrayWithLength(10);
var arr1000 = arrayWithLength(1000);
var arr1000000 = arrayWithLength(1000000);
var set10 = new Set(arr10);
var set1000 = new Set(arr1000);
var set1000000 = new Set(arr1000000);

Tests:

Filter arr10
arr10.filter(i => i === 5);
Filter set10
set10.delete(5);
Filter arr1000
arr1000.filter(i => i === 500);
Filter set1000
set1000.delete(500);
Filter arr1000000
arr1000000.filter(i => i === 500000);
Filter set1000000
set1000000.delete(500000);
