Don't do much JS, but this is actually what makes me the most sad. My formative programming years were during an era where there were many competing technologies on most given platforms. Now days, if I do mobile iOS, I have to do Swift, Kotlin for Android, and as you say JS for browsers. I wish we lived in a world where the platform didn't design the stack so much.
