Somehow, many frontend libs and frameworks decided to adopt this new thing, called Signals.
Vue had something that feels like signals since Composition API came out.
Preact, SolidJS, and Angular all have singals now.
I think it is a good thing that these frameworks have such similarities.
Most of RxJS code that I saw was overly complex and unasked for, to be honest.
Yes, RxJS is a powerful tool, but it seems to me that it was used like a golden hammer.
What frustrates me is that React team decided NOT to adopt this.
