Considering the big three frameworks are React (6 years), Angular (3+ years), AngularJS (9 years, deprecated) and Vue (5+ years) .. the churn really isn't what it once was. Yes, there are new options popping in and out, but even hyperapp and inferno are 2yo since 1.0.

Not all things have stood still, that said the frameworks are definitely still around, and barring a relatively few breaking changes, the past 3-5 years have been relatively stable now. Yeah, you can do react functional components with hooks, but the class syntax still works.
