Script Preparation code:

var dicr = {};
for (var i = 0; i < 1000; i++) {
	var	key1= Math.floor(Math.random() * 1000);
	var	key2= Math.floor(Math.random() * 1000);
    dicr[`${key1}_${key1}`] = key2;
}

Tests:

reflact
for (var i = 0; i < 1000; i++) { const res = Reflect.ownKeys(dicr) }
objectKeys
for (var i = 0; i < 1000; i++) { const res = Object.keys(dicr) }
