Why use `Reflect.get(target, key, receiver)` inside a `Proxy` `get` trap?

✓Correct answer: It performs the default operation with the correct receiver, so getters see the proxy as this
2It is required syntax; traps fail without it
3It makes the proxy faster

Explanation

Returning target[key] calls getters with this === target, bypassing the proxy (and its tracking). Vue's reactivity uses Reflect for this reason.
