Flux? Javascript has been "fluxing" for almost 30 years. Unpleasant chaos has to become your friend.
It is really unappealing and driven by "smart" people.
1. The "tutorials" are terrible. 2. The tooling - webpack etc - is terrible. 3. Things change too quickly. 4. There are an absurd number of technical layers trying to make frontend "safe" like backend EG typescript.
I like react as long as I am the only author involved. All the FE devs I've been forced to work with pull in an asinine number of external dependencies, weave painfully elaborate webpack setups, among many other things. I can't stand it.
