A DEV Community article argues that TypeScript functions as a debugging assistant, documentation system, and code safety net for JavaScript developers. It outlines ten specific habits to build, starting with enabling strict mode in tsconfig.json to enforce safety checks and catch errors early.

The guide emphasizes avoiding the `any` type, which defeats TypeScript's purpose, and instead using unknown, never, or union types. It recommends defining interfaces for scalable code structures and leveraging built-in utility types like Pick and Omit to keep definitions DRY and maintainable.

Developers should narrow union types with type guards and explicitly type function returns for clarity. Using enums for constants and generics for reusable logic are also key. The final advice is to let TypeScript's inference engine work where possible, only adding explicit types to improve readability and prevent bugs.
