Cool, but as someone who does mainly backend and only rarely tries to do some FE myself (because, come on, you are supposed to be at least somewhat full-stack!)

Cool, but as someone who does mainly backend and only rarely tries to do some FE myself (because, come on, you are supposed to be at least somewhat full-stack!), I feel like what I actually missed over the last 10 years is the current consensus on go-to tools/frameworks/libraries, both JS and CSS. Some "best practices 2021" tutorial would be way more valuable to me, but somehow I can never find one.
