Benchmark: for-in vs object.keys4

Script Preparation code:

var obj = {
    item1: { isTexture: true },
    item2: { isTexture: false },
    item3: { isTexture: true },
    item4: { isTexture: false },
    item5: { isTexture: true },
    item6: { isTexture: false },
    item7: { isTexture: true }
};

Tests:

for-in
for (var i=10000; i > 0; i--) { let texturesForIn = []; for (const key in window.fakeData) { const value = window.fakeData[key]; if (value && value.isTexture) { texturesForIn.push(value); } } }
Object.keys
for (var i=10000; i > 0; i--) { let texturesObjectKeys = []; const keys = Object.keys(window.fakeData); for (let i = 0; i < keys.length; i++) { const key = keys[i]; const value = window.fakeData[key]; if (value && value.isTexture) { texturesObjectKeys.push(value); } } }
