Tuple Patterns

πŸ‘¨β€πŸ’Ό Excellent! You've mastered tuple return patterns.
πŸ¦‰ The [value, error] or [value, success] pattern is common in TypeScript. It's inspired by Go's error handling pattern.
Benefits:
  • Forces callers to handle both success and failure
  • No need for try/catch in many cases
  • Types are explicit about what can happen
You'll see this pattern used in many libraries and APIs.
