What problem does it solve?
The non-null assertion operator (!) bypasses TypeScript's safety checks and can lead to runtime errors. This Skill promotes safer alternatives like optional chaining, nullish coalescing, and type guards.
Core Features & Use Cases
- Safe alternatives to ! (optional chaining, nullish coalescing)
- Type guards to narrow types safely
- Early returns and assertion functions for explicit safety
Quick Start
Replace uses of ! with safe alternatives and add a type guard for runtime safety.
