03. Literal Types/Elaboration

Break Literal Types
👨‍💼 Nice work! You used literal types to model exact values and as const to preserve them in arrays and objects.
Key takeaways:
  • Literal types let you encode specific values as types
  • as const prevents widening and preserves exact values
  • Config objects can become the source of truth for derived types
