It's really hard to be sure, but my pet theory is that frontend tech has been rapidly evolving since it had to solve some real problems that are relatively new at scale:

- Work with reactive variables

- Combine three different languages

- Write modular code

- Enable highly response designs

The target platform (the web) doesn't natively support all of these things elegantly, and maybe for good reasons.

I've got the feeling that frontend frameworks are starting to converge to some consensus on some of these things (e.g. signals), and I hope the next decade will be more stable than the last.

That is my feeling/hope as well. Modules were a big win, even if the advantage was felt mostly in bundlers and it’s just now arriving in browsers and node. Hopefully signals will be a smoother thing
