I think dread is warranted. Seeing Coffescript is enough for me to completely disregard and abandon a project I otherwise perceived interesting.
It introduces indirection and complexity, while adding zero value. As such it's on overall a negative value proposition, and that's everything it takes for me to decide something is not worth it.
I find it a perfectly rational decision and attitude.
While I'm not a fan per se, at least other transpired languages like typescript and clojurescript at least adds new capabilities to justify the additional complexity.
Anyways, I do appreciate the response.
