Script Preparation code:

var objects = [];
for (var i = 0; i < 10000; i++) {
    var idx = Math.floor(Math.random() * 1000);
    objects.push({
        index: idx
    });
}

var idx = Math.floor(Math.random() * 1000);

Tests:

indexOf
var objectIndices = []; for (var i = 0; i < 10000; i++) { objectIndices.push(objects[i].index); } var objectIdx = objectIndices.indexOf(idx); var tempResult = objects[objectIdx];
find
var tempResult = objects.find(v => v.index === idx);
