Benchmark: forinvsobjectkeys

Script Preparation code:

const fakeData = {
    item1: { isTexture: true },
    item2: { isTexture: false },
    item3: { isTexture: true },
    item4: { isTexture: false },
    item5: { isTexture: true }
};

Tests:

forin
let textures = []; const startForIn = performance.now(); for (const key in fakeData) { const value = fakeData[key]; if (value && value.isTexture) { textures.push(value); } } const endForIn = performance.now(); console.log(`for-in loop execution time: ${endForIn - startForIn} ms`);
objectkeys
textures = []; // 重置数组 const startObjectKeys = performance.now(); const keys = Object.keys(fakeData); for (let i = 0; i < keys.length; i++) { const key = keys[i]; const value = fakeData[key]; if (value && value.isTexture) { textures.push(value); } } const endObjectKeys = performance.now(); console.log(`Object.keys loop execution time: ${endObjectKeys - startObjectKeys} ms`);
