Sorted keys vs non-sorted keys performance

var keys = [];
var results = [];
var keyCount = 100;
var iterations = 10000;

//generate keys 0 to <keycount>
for (var i=0; i < keyCount; i++) {
    keys.push(i);
    results.push({ id: i })
}

//order keys randomly
keys.sort(k => Math.random()-0.5);

//non-sorted keys requiring reconciliation
var startDate = new Date();

for (var j=0; j < iterations; j++) {
    var orderedResults = [];
    for (var i=0; i < keys.length; i++) {
        orderedResults.push(results.filter(r => r.id == keys[i])[0]);
    }
}
console.log('Non-sorted: ' + (new Date() - startDate));

//sorted keys
startDate = new Date();
var sortFunction = (a, b) => a.id-b.id;

for (var j=0; j < iterations; j++) {
    keys.sort(sortFunction);
    results.sort(sortFunction);
}

console.log('----Sorted: ' + (new Date() - startDate));
