The main problems as I perceive it:
- unreadable generated code (aka, hard to debug in the browser)
- not very accessible (complex docs, unclear what it is or how to use it)
some real problems with jsoo are (non exhaustive list)
- "heavy" FFI (both in term of setup and syntax)
- the output is a big single .js file, which doesn't allow reloading of a single component and doesn't integrate well with stuff like webpack
- slower compilation time
- lacking documentation for the javascript audience
