Elm... And not to forget PureScript... and to a lesser extend ReasonML (by which you can still use React and JSX)... and Haskell/GHCJS. There are quite a lot of ways to seek refuge from both type scarcity and the "semicolon" line noise that was mentioned.

Here some benchmarks for several of the FWs that are popular in these languages (Elm has the FW built-in, ReasonML-React is missing but should be close to React.js).
