JS Practice — Built-in Objects

Proxy() — typeof

📖 Usage Example

const target = { value: 42 }
const p = new Proxy(target, {
  get: (t, k) => k in t ? t[k] : 'default'
})
console.log(p.value)   // → 42
console.log(p.missing) // → 'default'

new Proxy(target, handler) creates a proxy that intercepts operations on the target object using trap methods in the handler.

typeof a Proxy

typeof new Proxy({}, {}) returns 'object' because the proxy wraps a plain object.

Challenge: Verify that typeof new Proxy({}, {}) returns 'object'.

💡 Hints (1)

• `typeof` on a proxy of an object returns `'object'`.
