WeakRefbeginner

WeakRef — deref preserves properties

📖 Usage Example

const obj = { name: 'test' }
const ref = new WeakRef(obj)
obj.name  // → 'test'

Holding a WeakRef does not keep the object alive on its own.

WeakRef Property Access

new WeakRef({x: 1}).deref().x === 1.

Challenge: Verify property access through deref.
