Benchmark: Object key sorting: forEach vs Object.fromEntries

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const testObj = {};
for (let i = 0; i < 1000; i++) {
  testObj[`key_${Math.random().toString(36).substring(7)}`] = Math.random();
}

Tests:

forEach
function keySortedForEach(obj) { const sortedKeys = Object.keys(obj).sort(); const sortedObj = {}; sortedKeys.forEach(key => { sortedObj[key] = obj[key]; }); return sortedObj; } // Benchmark 1 keySortedForEach(testObj);
Object.fromEntries
function keySortedFromEntries(obj) { return Object.fromEntries( Object.entries(obj).sort(([keyA], [keyB]) => keyA.localeCompare(keyB)) ); } // Benchmark 2 keySortedFromEntries(testObj);
