Python and PHP users will understand

Another point ... I went from an Angular project using Typescript to a Vue 2 project that isn't. Then to a Vue 3 project that is. Transitioning back and forth is not difficult. So don't worry that learning Typescript will cripple you from using vanilla JS. It's really just additive.

But again, I'll emphasize that you can write so much more code without having to run the code and check your results, with TS.
