Sure, it's probably more prominent for someone like me who doesn't code for a day job. So it's not just limited to the context switching associated with syntax, it's the peripheral things like language / framework conventions, packaging systems, etc. I am definitely curious about other languages, but I don't have the inclination to spend the time to learn them well enough to build something I would put on the internet. At least not when I can put together a pretty performant / scalable app with a modicum of effort using this stack. These things may not be of much significance to a seasoned polyglot dev, but for someone who only really knows JS and is an infrastructure guy by trade, it makes a big difference :)
