non-null-assertion

What problem does it solve?

TypeScript code often relies on the non-null assertion operator (!) which can mask undefined values and lead to runtime errors; this Skill promotes safer coding by eliminating the use of ! and guiding toward safer patterns such as optional chaining and explicit guards.

Core Features & Use Cases

• Encourages optional chaining, type guards, and nullish checks to safely handle nullable values.
• Provides guidelines for reviewing TypeScript code to avoid forced null assertions.
• Helps teams enforce consistent null-safety practices across codebases.

Quick Start

Replace occurrences of the non-null assertion with safe alternatives and validate code paths.
