Enforce TypeScript best practices by adopting const-backed types, flat interfaces, and safe handling of unknown values. This approach reduces runtime errors by ensuring a single source of truth for definitions and strictly avoiding the any type.

The best way to structure TypeScript interfaces for reusability is to favor flat interfaces with referenced sub-interfaces. This avoids inline nesting, improves code maintainability, and allows individual sub-interfaces to be reused across different modules.

Handle unknown values safely in TypeScript by replacing any with unknown and applying type guards. Type guards narrow values at runtime to ensure type safety, while generics provide flexible APIs without sacrificing strict typing constraints.

You need utility types like Pick, Omit, Partial, and Record in a TypeScript codebase to transform existing types into new variants. They enable flexible type definitions without code duplication, allowing you to create required, readonly, or partial structures.

Refactor an existing TypeScript project by creating const objects first to derive types, flattening nested interfaces, and replacing any with unknown. Apply type guards and import types for clear dependencies to achieve a strict, maintainable codebase.

Use const-backed types in TypeScript to establish a single source of truth that provides both runtime values and type definitions. This pattern improves autocomplete, simplifies refactoring, and ensures your runtime values remain strictly aligned with your type definitions.
