Benchmark: object with define property vs Proxy get

Tests:

Proxy
const queryResults = { a: {}, b: [2, 3, 4], c: 3, d: { a: 1, b: [], }, }; const trackedResults = new Proxy(queryResults, { get(target, prop, receiver) { return Reflect.get(target, prop, receiver); } }); trackedResults.d
brand new object
const queryResults = { a: {}, b: [2, 3, 4], c: 3, d: { a: 1, b: [], }, }; const trackedResults = {}; for (const key of Object.keys(queryResults)) { Object.defineProperty(trackedResults, key, { configurable: false, enumerable: true, get() { return queryResults[key]; }, }); } trackedResults.d
