For personal projects, I did. I learnt basic Haskell knowledge so gradually I realized JavaScript is troublesome. After learning more about functional programming and using Clojure for a while, I believed I need ClojureScript as the basis of uni-directional data flow. So I did. ClojureScript might be inadequate for production, but for personal apps it's mature enough.
In JavaScript, immutability is just awkward. Users embrace uni-directional data flow but frequently go wrong because of the inconsistency. Also I want a pure enough language to make sure the DOM DSL is simple. ClojureScript is like being designed for that, even though it wasn't.
