I’m also starting to feel like if anything will dethrone React, it’ll probably be Vue or Svelte.
I think Vue's reactivity system just fundamentally doesn't work which is why Vue 3 is basically an entirely new paradigm/framework trying to masquerade as an update. I have a feeling its going to split the community and end the way angular did.
I haven't used Svelte at all but it looks very interesting.
I then tried React and it just kind of made sense. Since then from the sidelines I've heard Angular has gotten much better but personally don't see any reason to use anything other than React at this point in time.
