Benchmark: Object value comparison vs array of object value comparison with different loops v1

Script Preparation code:

var items = Array.from(Array(1000), (_, x) => ({
    key: x,
    value1: Math.random() * 1000,
    value2: Math.random() * 1000
}));

var objContainer = {};
var arrContainer = [];

for (let i = 100; i >= 0; i--) {
    const index = Math.floor(Math.random() * 1000);
    const item = items[index];
    objContainer[item.key] = item;
    arrContainer.push(item)
}

Tests:

Object, for-in
var result = []; for (var k in objContainer) { if (objContainer[k].value1 >= 0 && objContainer[k].value1 <= 499 && objContainer[k].value2 >= 500 && objContainer[k].value2 <= 999) { result.push(k); } }
Array, for-of
var result = []; for (var item of arrContainer) { if (item.value1 >= 0 && item.value1 <= 499 && item.value2 >= 500 && item.value2 <= 999) { result.push(item.key); } }
Object, for
var result = []; var keys = Object.keys(objContainer); for (var i = 0; i < keys.length; i++) { if (objContainer[keys[i]].value1 >= 0 && objContainer[keys[i]].value1 <= 499 && objContainer[keys[i]].value2 >= 500 && objContainer[keys[i]].value2 <= 999) { result.push(keys[i]); } }
Array, for
var result = []; for (var i = 0; i < arrContainer.length; i++) { if (arrContainer[i].value1 >= 0 && arrContainer[i].value1 <= 499 && arrContainer[i].value2 >= 500 && arrContainer[i].value2 <= 999) { result.push(arrContainer[i].key); } }
