Your point is taken although I wouldn't say Node qualifies as the latest trend at this point. It feels like it has moved on to "just another tool to choose from" status to me. I suppose trendiness is relative but if you use a Google Trends search for "Isomorphic JavaScript" as a proxy for Node's trendiness[1], it was at its trendiest in 2016 and has fallen off quite a bit.
