Script Preparation code:

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

Tests:

for (let i = 0; i < cnt; i++) { proxy[i] }
Prototype
for (let i = 0; i < cnt; i++) { protoObj[i] }
Direct
for (let i = 0; i < cnt; i++) { obj[i] }
