Although you've been downvoted, I think your question is fair, so I'll try to give it a fair answer. In this discussion, when we talk about value, I think it makes sense to look at value in the sense of how valuable a skill is to the longevity of your career. In that sense, JavaScript has some upsides - it's everywhere, and will likely continue to be everywhere. There will be lots of demand for JavaScript development. But because JavaScript is everywhere, tons of people know it, and tons of people are learning it. So although there will be lots of demand for JS development, if you're a JS developer, there will also be a ton of people offering a skillset that is broadly similar to yours. As you mentioned, the demand for something like Linux driver developers is tiny in comparison to the demand for JS developers. But the talent pool is relatively tiny, too. So it might be easier for you to differentiate yourself because when an employer is looking for someone with your skillset, they're not going to have to wade through hundreds of resumes from people who look pretty qualified. In general, I think it's most valuable to specialize in solving a certain type of problem, where programming just happens to usually be the best way of solving it. It's often easier to sell yourself as a solver of specific kinds of problems than it is to sell yourself as a generalist with experience in JS, HTML, CSS, etc.
