Julia punches well above it's weight in libraries, especially for datascience and has the best online community I've ever been a part of. Googling an error in julia definitely won't give you nearly as many StackOverflow hits, but the community Discourse, Slack and Zulip channels are amazingly responsive and helpful.

I think a big advantage of Julia is that it has a unusually high ratio of domain experts to newbies, and those domain experts are very helpful caring people. It's quite easy to get tailored, detailed personalized help from someone.

This advantage will probably fade as the community grows, but at least for now, it's fantastic.
