I haven't really deeply thought about frontend JS for many years.

Back then the question we were looking at was whether it would be good idea to move away from SAP UI5. The alternatives back then where React, Angular and Vue.

The conclusion we came to was that it was definitely worth to migrate, but to what was not so easy to agree on.

Right now I am working with a legacy Java codebase that was based on RxJava. And every single day I am cursing the people that made that decision. It seems so obviously a bad idea. And the only thing that lets me keep my sanity is remembering that every decision only becomes obvious with hindsight.

So I guess the only thing I can contribute is that it could always be worse and sometimes making the bold and seemingly innovative decision comes back many years later to bite other people.
