Backend has changed hugely with the advent of docker, kubernetes, cloud in general. Languages as well are changing a lot: golang, rust, hell even Java started a new release cadence with new stuff (lambdas, streams) You don't have to move to the latest way if doing things all the time in either front or backend. You do not have to follow the latest fashions. There are loads of backend frameworks that no one remembers because Django/ruby/spring became "good enough" and won, but back in the day there were many competitor frameworks for what was then frontend development. But we've largely forgotten about them all, as we will largely forget about the current gaggle of js frameworks once something "wins" with a good enough solution. Tl;Dr - The way we develop frontend has changed from largely server side to now being SPAs. Things will calm down in the coming years as one framework becomes "good enough" and ends up becoming the de jour standard. The knowledge and concepts never change though. What we're doing today in Vue and RxJs etc is as old as the hills as far as computer science is concerned.
