typescript

TypeScript flat interfaces replace inline nested object types with dedicated, shallow interface definitions. This structure improves code readability and refactoring by preventing deeply nested type dependencies.

Runtime-safe string literal unions in TypeScript are created by defining const objects using the as const assertion. Types are then derived from these objects to improve autocomplete and ensure refactoring consistency.

The best way to use TypeScript utility types is applying them for precise type transformations alongside type guards. This provides reusable patterns for modifying existing types rather than creating redundant, inconsistent type models.

TypeScript type-only imports use the import type syntax to keep dependencies clear. They ensure that only type definitions are imported at compile time, preventing unintended runtime module execution.

TypeScript generics should be used instead of any when building flexible functions. Generics maintain strict typing by preserving input types across the function, whereas any disables type checking completely.
