Yeah, dropping typescript and then codifying type information in jsdoc is comical.
The only thing I would say about your experience is that “dropping TS for go” is a little bit misleading, and it doesn’t really sound like it bears on the general debate of “TS vs. JS” - go and other static languages generally fit a different niche in my opinion, and can be a better option for certain kinds of systems.
If you’re building anything of even moderate complexity, or with more than one person, you really need the types and modularity that TS provides.
I guess it’s also worth noting that JS has actually been influenced/adopted some key features from TS over the years, so it’s possible to do a few things with it to make stuff that’s a bit more maintainable.
This is an professional experience thing.
Types support “programming at scale” - scale in the sense of larger code based or multiple people contributing.
If you’re hacking away at a script for a web page, then yeah, have at it.
If you’re supporting more than a few hundred lines of code or working on a team, you need types to codify and communicate information that can be verified with a compiler.
Whenever you see a larger codebase that is not strongly (or statically) typed, you generally will see unit tests that are verifying the types/structure of outputs.
