javascript delenda est
Or: Ceterum autem censeo Javascriptum esse delendam.
But I think the parent refers to the famous quote by Cato Censorius who demanded Carthago to be destroyed. He used the „accusativo cum infinitivo“ construct to express his personal desire not something that actually happened to this point. So it should read:
[Ceterum censeo] Javascriptum esse delendum.
