Benchmark: property access: object with define property vs Proxy get vs plain object 2

Script Preparation code:

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

Tests:

Proxy
window.trackedResultsProxy.d.a + window.trackedResultsProxy.c
defineProperty
window.trackedResultsDefineProperty.d.a + window.trackedResultsDefineProperty.c
getter
window.trackedResultsGetter.d.a + window.trackedResultsGetter.c
Proxy w/ Reflection
window.trackedResultsReflect.d.a + window.trackedResultsReflect.c
Control (plain object access)
window.queryResults.d.a + window.queryResults.c
