I find it amazing how many different software development frameworks are out there.
After all these years I still haven't bothered to look up what React is, and I probably will never need to.
I will probably never get to maintain a codebase that uses it.
So if being 'up-to-date' isn't something I will go for, how do I measure myself as a developer? I think I will go for something like 'having made a lot more regular people happy than I have frustrated'.
