Script Preparation code:

var obj = {}
var cnt = 1000

for (let i = 0; i < cnt; i++) {
  obj[i] = i + ''
}

var proxyReflect = new Proxy(obj, {
  get(obj, prop, reciever) {
    return Reflect.get(obj, prop, reciever)
  }
})

var proxy = new Proxy(obj, {
  get(obj, prop, reciever) {
    return obj[prop]
  }
})

var protoObj = Object.create(obj, {})
