TL;DR "It’s what I know best"<p>~FIN~<p>My two cents:<p>Coming from stuff like Java and PHP I like JavaScript quite much. Async stuff bit of a pain in other languages I used, but JS integrates it nicely within its event loop. With Tasks, Promises and Observables it even seems to get managable. And with the Web and its browsers it seems to be the open platform for applications we have today.<p>Problems I saw in the past:<p>Founders using popular languages to get more people from the job marked, but I had the experience, you can use languages to pre-filter applicants. I assume the average JavaScript developer isn't as good as the average C++ or even Haskell developer.<p>But I'm happy about my switch to JavaScript 5 years ago, much jobs for mee~ :)
