Benchmark: Proxy vs defineProperty v2

Script Preparation code:

object = { value: 'data', getData() {return this.value;}, get data() { return this.value } };
Object.defineProperty(object, 'dataProperty', {
  get() { return this.value; }
});
proxy = new Proxy(object, {})
proxyWithReflectHandler = new Proxy(object, {
	get(target, prop, receiver) {
    	return Reflect.get(target, prop, receiver)
    }
})
proxyWithHandler = new Proxy(object, {
	get(target, prop, receiver) {
    	return object[prop];
    }
})

Tests:

Object access
object.value;
Proxy access
proxy.value
Proxy with get handler access
proxyWithHandler.value
Use of simple getter
object.getData();
Use of defineProperty
object.dataProperty;
Proxy with get reflect handler access
proxyWithReflectHandler.value
object get data
object.data;
