JS Practice — Built-in Objects

Symbol() — cannot use new

📖 Usage Example

Symbol('ok')   // works fine
try {
  new Symbol()  // TypeError!
} catch (e) {
  console.log(e instanceof TypeError)  // → true
}

Symbol is a primitive factory — calling it with new throws a TypeError.

Symbol Cannot Be Constructed with new

Unlike most built-ins, Symbol is a function — calling it with new throws a TypeError.

Challenge: Confirm that new Symbol() throws.
