Type safety isn’t worth having more complex prototypes, and having to keep up with both JS and Tyoescript, for us.
It’s very easy and forgiving to do a proof of concept though, because it integrates so easily into your existing code base.
Just be sure it actually adds real value and isn’t something you do for hype.
I’d certainly utilise it if we were building something as complex as VSC, but we aren’t, and I think it’s important to keep in mind that typescript isn’t all positive gains but that it also has downsides.
