I love React and write it, in Typescript, on a daily basis. However:
- It starts you off with about 40kB of minified gzipped javascript; some developers feel that it's too much.
- It is not and probably never will be the most performant framework out there, which upsets quite a few people (although the work that the React core team is doing with Concurrent Mode probably means that from the end user's perspective React will feel fast enough).
- It has become the default way for many frontend developers to write JavaScript; I know I am personally guilty of that. This generates a lot of resentment from more experienced developers who have learned to prioritise minimalistic JavaScript bundles over developer experience.
