As soon as you add TS to the mix, you have to deal with TS compiler not being able to output run-ready JS (or has that changed by now?), because of JS issues with modules and you need a "bundler", yet another accidental complexity, and one that is often a nightmare to configure. Then some drive-by person will want you to minify all the things and you add another unnecessary complexity.

TS is great mostly. But it definitely comes at a cost.

I think the situation with TS has improved, but yes, I only really use it with a bundler where that isn't an issue - in this case, Vite. But typically Vite does most of the things you'll need out of the box, and I find I rarely need to think about it, so it's the sort of complexity I'm mostly happy to take on.
