I started developing webapps back in the late 90s when I was in high school using Perl, and I've worked with tons of technologies up till around 2014 or so when I shifted into almost pure backend work and lost touch with modern frontend development.

I'm now learning how modern frontend development is done (for both personal and professional projects), so I may not know the specific tools, technologies, or terms but I can say "whatever the equivalent of XYZ is" and the models will translate for me. If I say "run pytype" it will tell me "we're using mypy - i'll run that checker for you".

If you can express what problem you're trying to solve, that will get you most of the way - and then you can refine by asking questions. "I think I need something like Redis for caching things - do people still use that? Is there a simpler more modern version that is the new standard? Do we already have company docs suggesting what to use?"
