I've been programming for a long time and TypeScript has been a slam dunk for me. It makes programming large web apps actually considerably more manageable.

Unfortunately I spend a lot of time defending the merits of static typing to my co-workers. At the same time they're going on about how unit tests are important, while static typing eliminates entire classes of errors and they don't get it for some reason. Unit tests while important don't prevent type errors, and if you tried using them for that you'd have orders of magnitude more tests to write.

I feel like I'm taking crazy pills having to defend static typing while every dynamic language I've used for any project of any considerable size has been a complete nightmare to manage. At this point I feel like a lot of new coders coming out of school just haven't written anything large enough yet and maybe that's why they don't see the point.
