URLSearchParams#toString() — serializes params

📖 Usage Example

const p = new URLSearchParams('x=1')
p.delete('z')  // no-op if key doesn't exist

delete() is safe to call even if the key does not exist.

URLSearchParams#toString()

params.toString() returns the params serialized as a query string (without the leading ?).

Challenge: Verify the serialized output.
