JS Practice — Built-in Objects

Proxy — typeof Proxy

📖 Usage Example

const log = []
const p = new Proxy({}, {
  deleteProperty: (t, k) => { log.push(k); return true }
})
delete p.foo
console.log(log) // → ['foo']

The deleteProperty trap intercepts delete operations, allowing custom logic when a property is deleted from a proxy.

typeof Proxy

Proxy is a built-in constructor, so typeof Proxy returns 'function'.

Challenge: Verify that typeof Proxy returns 'function'.
