typescript

Avoid any in TypeScript by using unknown for uncertain inputs and applying type guards. Combine this with utility types and explicit imports to maintain type safety without resorting to unsafe type assertions or losing maintainability.

Structure TypeScript interfaces by keeping them flat, one-level-deep. This pattern creates simpler, scalable types across your codebase, making them easier to maintain and refactor compared to deeply nested interface structures.

Create a single source of truth in TypeScript using the const types pattern. Define a const object as your source, then derive your types using typeof and keyof to sync runtime values and type definitions automatically.

Use type guards and utility types in TypeScript refactoring when implementing strong typing and flat interfaces. They are required to satisfy strict type safety, narrow unknown types, and prevent any usage during application refactoring.

Yes, use const assertions to improve TypeScript maintainability by locking literal types and deriving types from const objects. This approach enforces robust typing patterns and reduces bugs by keeping runtime values and types synchronized.
