TypeScript Development Partners
TypeScript is JavaScript with static types, and it has become the de facto standard for production web applications. With over 85% adoption among professional JavaScript developers, TypeScript catches entire categories of bugs at compile time that would otherwise surface in production. For startups, TypeScript is non-negotiable for codebases that need to scale — it dramatically reduces onboarding time for new engineers, improves IDE autocomplete, and makes refactoring safe. Hire senior TypeScript engineers and fractional CTOs who ship production-grade code and mentor your team.
