After a decade of writing JavaScript, I've come to believe that TypeScript's type system saves more time than it costs, despite the initial learning curve. Teams I've worked with who adopted it spent less time debugging runtime errors and more time refactoring confidently—our bug rate in production dropped by roughly 30% after the switch. I know some argue the extra syntax slows down prototyping, but in the long run, that overhead pays off. So, is TypeScript truly a net win for software development, or is it just unnecessary complexity for small projects?
