📝 Walkthrough

Walkthrough

The component replaces Difficulty and Direction enums with union-based types. Template handlers use string literals. The component removes public enum properties, updates the direction signal type, and simplifies directionLabel.

Changes

Union type migration

Layer / File(s)	Summary
Type definitions and signal state apps/typescript/47-enums-vs-union-types/src/app/app.component.ts	Difficulty now uses a const object with a derived union type. Direction now uses a mapped type. The direction signal stores direction keys and the component no longer exposes the type objects.
Template and label integration apps/typescript/47-enums-vs-union-types/src/app/app.component.ts	Difficulty and direction handlers pass string literals. directionLabel uses a null check and string interpolation.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 80e5a

The enum migration currently prevents the challenge application from compiling due to a duplicate type alias, so it should be corrected before merge.
