Why TypeScript is worth it

TypeScript is JavaScript with static types. That small addition has an outsized impact: entire categories of bugs — typos, wrong shapes, missing null checks — are caught the moment you write the code, not in production.

Confidence at scale

As a codebase grows, types act as living documentation. Your editor knows exactly what every function expects and returns, so refactoring becomes safe and autocomplete becomes genuinely useful.

Gradual and pragmatic

You do not have to type everything at once. TypeScript is designed to be adopted incrementally, and modern frameworks like Next.js support it natively. The result is a frontend that is faster to build and much safer to change.
