You should probably just be whatever sort of developer gets you the job. If someone posted a listing for a "JavaScript Engineer", they probably don't know the difference between a good programmer who happens to have used JS for a while and someone who exclusively uses JS. So what the hell, go ahead and call me a JavaScript engineer if it helps you sleep better and justify hiring me to whoever you report to.
