I avoid TypeScript because I already feel the tidal forces on me emanating from Redmond. We are currently working on an education app in C# and it’s simple and delightful to do it and our front end is so easy to do. I also kind of like Typescript too, but as the author here points out, then you’re married to this tooling and … all of these autogenerated files.
So for me I guess I’m saying the threshold is lower just because I already feel like I need to keep some diversity in our codebase.
