I love using ClojureScript but one other downside is the lack of ClojureScript jobs. There are thousands of JS jobs right now but how many cljs jobs are hiring? Tens?

That sucks because cljs is great but it's probably the biggest incentive for sticking with JS.

It's not relevant how many companies are hiring for that, as long as someone is.

Clojure is growing fast, and a complaint I'm hearing consistently lately is that there are not enough clj/s devs around.

market size is relevant, are the people doing the complaining willing to pay $$$ for cljs devs? I was on the market last winter and could only find $$ (baby startups) which was a 50% cut in rate to work in cljs. BTW I am about to start looking again, contact info in profile
