JS Practice — Built-in Objects

Map get() — object key reference equality

📖 Usage Example

const m = new Map([['name', 'Alice']])
m.get('name')    // → 'Alice'
m.get('missing') // → undefined

Use Map.get() to retrieve the value associated with a key.

Map.prototype.get()

Object keys are compared by reference. A different object with the same structure won't match.

Challenge: Verify that object key lookup uses reference equality.
