I can't personally say with any sort of authority if JavaScript is the root cause of OP's dilemma because beyond a brief stint coding in JavaScript for Yahoo Widgets on early "Smart TVs" (due to a rather unexpected series of events) I haven't used JS regularly for any extended period of time, but I can say that I'm 49 and still really enjoy coding (these days mostly in Kotlin/Android and Go), so I can say falling out of love with coding as you age isn't universal.
