To avoid using any in TypeScript, use the unknown type or generics for better type safety. This enforces strict type checks and prevents runtime errors by requiring explicit type narrowing.

Writing flat interfaces in TypeScript involves avoiding excessive nesting to promote clear and readable definitions. You should structure interface properties at a single level whenever possible.

Apply the const types pattern by ensuring a single source of truth for constants and their types. This pattern maintains strict alignment between constant values and their inferred types.

You need utility types and type guards in TypeScript when performing type manipulation and runtime checks. These features allow you to safely narrow broad types and transform existing type definitions.

Strict mode in TypeScript works seamlessly with generics and interfaces to enforce type-safe code. It ensures that flat interfaces and generic type parameters are rigorously checked at compile time.
