What is the difference between any and unknown?

Q: What is the difference between any and unknown?

**`any`** opts out of type checking entirely — anything goes. **`unknown`** is the type-safe counterpart: you can assign anything to it, but you must narrow it (via `typeof`, checks, or assertions) before using it. Prefer `unknown` to keep type safety.
