YMMV, but I’m less worried about “clean and fun” and much more worried about rugged and correct. TypeScript makes it easier to unambiguously express intent both inside an application and when talking to external modules. Some parts of the syntax are unfortunate but I care about that a lot less than I do not having my systems break.

I’d switch and I wouldn’t look back. I did switch my focus of learning and use, albeit from Ruby and Kotlin (which is better than nothing but nominative typing is insufficient IMO) to TypeScript, and it was among the best decisions I’ve made in my professional career.
