05. Any vs Unknown/Elaboration

Break Any Vs Unknown
Break Any Vs Unknown
👨‍💼 You understand the difference between any and unknown!
You learned:
  • 🚨 any disables type checking—dangerous!
  • 🛡️ unknown requires narrowing—safe!
  • ✅ Best practice: Use unknown for external data
🦉 When you encounter any in code, ask:
  • Can this be unknown instead?
  • What type should this actually be?
  • Is there a more specific type available?
Every any is a potential bug waiting to happen. Prefer unknown and narrow it properly.
🎉 Congratulations! You've completed the Type Safety workshop. You can now design types that make illegal states unrepresentable!
