No, because it's usually a few years old and already obsolete - the frameworks and the language have gone through a gazillion changes and what you did in 2021 suddenly no longer works at all.
Also, I know that people love to joke on modern software and JS in particular. But if you take react code from 2020 and drop it into a new react codebase it still works. Even class based components work. Yes, if you jumped on the newest framework bandwagon every time stuff will break all the time, but AI won’t be able to help you with that either. If you went for relatively stable frameworks, you can re use boilerplate completely or with relatively minimal adjustments
If you take a project from 2020 it's a bit of a pain to upgrade it.
I ran this prompt (and others like it) and it actually worked!
This code needs to be upgraded to the new
recommended JavaScript library from
Google. Figure out what that is and
then look up enough documentation to
port this code to it
