I'm maybe inheriting a #NodeJS project, as a part-time paying gig. I don't do node. I do the minimum amount of client-side JS to make something work.
If the project is sane, I'm confident I could skill up on-the-fly. If the project is terrible, I'd be in over my head. I don't have the expertise to judge, though.
If it was Python / Django, I'd be able to tell what I was in for in ten minutes.
Where do I look in a node project? What are best practices? What warning signs do I look for?
