TypeScript discriminated unions enable robust state management by combining literal types with object shapes, allowing pattern matching and safer conditional logic. This Skill provides examples of defining unions and implementing type guards to reduce runtime errors.

Best practices for TypeScript type definitions involve using interfaces and type aliases effectively, applying readonly for immutability, and defining optional properties. This Skill demonstrates these patterns to enhance code quality and maintainability in TypeScript projects.

Custom type guards in TypeScript are functions returning type predicates that allow safe narrowing of types in conditional logic. This Skill shows how to create and apply type guards alongside discriminated unions for more robust, type-safe code execution.

Handling nullability in TypeScript requires leveraging strict mode settings to catch potential null reference errors during compilation. This Skill covers strict mode configurations and nullability handling patterns to ensure higher code safety and prevent common runtime crashes.

Yes, this Skill provides TypeScript patterns suitable for React applications, specifically using discriminated unions and type guards for complex state management. These techniques help developers achieve fewer runtime errors and clearer component code.
