I picked up ClojureScript at the end of 2013. I was a C++ developer then in a small firm and was tasked to write a web frontend. Outsourcing that project had failed before (2 times iirc), so my boss bet on me to do it. I knew HTML and had written probably < 1000 lines of Javascript code in my life before. Anyway, I needed to write an interactive single page app (basically it was a visualization of simulation results), so I needed Javascript. But it was so frustrating to write Javascript (also, tooling was mediocre back then or I didn't know it). So at the same time, I stumbled over ClojureScript and had a try (I new Scheme before and was especially outraged by JS syntax quirks, so I hoped S-expressions would rescue me). With ClojureScript in 2013 I had a module system that handled dependencies, an emerging library ecosystem that had what I needed for that specific case, I was pretty happy. This was more advanced than what I got with JS (I might not have found the viable options for such stuff with JS, but at least information on them wasn't widely found then).

Last year I had another look at ClojureScript and it felt like a ghost town. This saddens me. There are a few inspiring talks now and then, but nothing I found worth using in a project.
