typescript

To configure TypeScript strict mode, apply a production-grade tsconfig approach that enforces strict compiler options, ensuring zero `any` usage and no unsafe assertions. This prevents runtime surprises and reduces type bugs in real codebases.

Choosing between type vs interface depends on your TypeScript type modeling needs; type is versatile for unions and primitives, while interface is extendable for object shapes. Apply disciplined conventions to ensure reliable generics and safe narrowing.

The best way to handle errors in TypeScript is modeling them via Result patterns or discriminated unions. This approach ensures safe runtime decisions and reliable narrowing, reducing inconsistent and unsafe TypeScript implementations.

Yes, Zod works with TypeScript to provide safer boundary validation. It validates external data inputs at runtime boundaries, complementing static type checking to prevent runtime surprises and enforce strict-mode friendly patterns.

Fix inconsistent TypeScript generics and narrowing by reviewing .ts and .tsx files to apply correct narrowing techniques and disciplined type modeling. This ensures reliable runtime decisions and eliminates unsafe type assertions.

Yes, you can use this workflow for debugging .js and .jsx files, as it auto-detects TypeScript and JavaScript contexts. It guides refactoring and review tasks to apply strict-mode-friendly patterns across mixed codebases.
