I remember attending NodeJS meetups in the local Engine Yard office buildings around 2012 before there was an extant local NodeJS community, so most of the attendees were coming from non-JS programming backgrounds. There was the odd Ruby and PHP dev, but the vast majority of the initial local NodeJS community here were Java people for some odd reason. I didn't really know much about the Java community, but my general impression of the Java-backgrounded presenters demoing NodeJS apps they'd cobbled together with libraries they didn't care to understand the internals of didn't give me good impressions.
I've never noticed any other strong connections between Java & JS communities online or elsewhere, this was a just general one-off (but strong) impression from local meetups.
