Enforces strict TypeScript practices to reduce type errors and improve safety in the game logic.

Replace `any` with `unknown` and use type guards to narrow types safely. This prevents implicit type coercion and forces explicit type checking, catching errors at compile time rather than runtime.
Use optional chaining and nullish coalescing instead of non-null assertions (`!`). This approach makes null-handling explicit in your code and prevents runtime crashes from accessing properties on null or undefined values.
Adopt the Result<T, E> pattern to represent success or failure explicitly. This eliminates type assertions and non-null assertions, making error paths type-safe and traceable throughout your game logic.
Exhaustive checking with type guards ensures all possible cases are handled at compile time. This catches logic gaps early, reduces runtime errors, and makes refactoring safer when types change.
Yes. Start by applying strict typing to new functions and refactor existing code gradually, replacing `any` types and assertions as you modify sections. This allows adoption without rewriting the entire codebase at once.
