Multiple Types (🏁 solution)
πŸ‘¨β€πŸ’Ό You've handled values that can be different types!
πŸ¦‰ Notice the narrowing techniques:
  • typeof for primitives (string, number, boolean)
  • instanceof for class instances (Error, Date)
  • Property checks for objects
TypeScript tracks what you've checked and narrows the type accordingly.
