- Javascript evolved, so you no longer need some crazy long template to support simple sentence like class extends
- TypesScript appears, and also benefit the js eco system with d.ts files. And it even become coffeescript's short coming
- Editor evolved, the editing experience is far better than before. The time typing long keywords can mostly compensated by auto-complete
But what will be the pain point that react can't resolve, other framework can and out weight any other benefits? I don't see that as for now
