TypeScript vs JavaScript: Our Team Has Picked a Side
After two years of building production applications, we have a clear winner. Here is why TypeScript is non-negotiable for us.
We started Relnov writing JavaScript. Within six months, we switched entirely to TypeScript. We have never looked back, and here is why.
“TypeScript catches bugs before they reach production.”
TypeScript catches bugs before they reach production. In our first month after switching, our production bug rate dropped by 40%. Not because we became better developers overnight but because the compiler caught our mistakes before users did.
The real value is not just type safety. It is the developer experience. Autocomplete, refactoring confidence, self-documenting code. TypeScript makes your codebase easier to navigate, especially as it grows.
Today, TypeScript is non-negotiable on every Relnov project. It is a small investment in setup time that pays dividends across the entire lifecycle of the product.
