I am what the cool kids call a fullstack developer these days. I use JavaScript in the browser and on the server. My build tools are written in JavaScript. I also write JavaScript for the database (in fact, I am a contributor to a database that is partially implemented in JavaScript). It's absolutely a JavaScript "problem", not one that's specific to web development. Web development is certainly where it's the most prominent but the problem itself isn't at all related to the web. JavaScript fatigue describes FOMO (Fear of Missing Out) as experienced by developers trying to keep up with rapid developments in tooling/libraries. It's not even really about the language, thanks to Elm, Reason and other new languages that joined the ecosystem. You're right that it has little to do with the language, but it also has little to do with the niche. Anyone interested in DevOps experienced some degree of FOMO when suddenly Puppet, Chef and Ansible became a thing (being fundamentally different but also mostly doing the same job). If you just started out with Linux before Ubuntu pretty much became the mainstream starting point, "distro fatigue" was almost certainly a thing. It's just plain old FOMO, but with a tweetable buzzword attached to it.
