Proxy Made With Reflect 4 Top May 2026

// BAD get(target, prop) { return target[prop]; // Ignores proxy inheritance } // GOOD get(target, prop, receiver) { return Reflect.get(target, prop, receiver); // Maintains correct this } Sometimes you need a proxy made with reflect that can be revoked. Use Proxy.revocable .

function createTransparentProxy(target) { return new Proxy(target, { get(target, prop, receiver) { return Reflect.get(target, prop, receiver); }, set(target, prop, value, receiver) { return Reflect.set(target, prop, value, receiver); }, has(target, prop) { return Reflect.has(target, prop); }, deleteProperty(target, prop) { return Reflect.deleteProperty(target, prop); }, apply(target, thisArg, argumentsList) { return Reflect.apply(target, thisArg, argumentsList); }, construct(target, argumentsList, newTarget) { return Reflect.construct(target, argumentsList, newTarget); } }); } Using Reflect ensures that if the target object has native getters or inherits from a prototype, the proxy respects those behaviors without additional code. One of the "top" use cases is logging without breaking the application logic. proxy made with reflect 4 top

console.log(heavyDB.query("SELECT * FROM users")); // Initializes + executes console.log(heavyDB.status); // No re-initialization // BAD get(target, prop) { return target[prop]; //
