You are spot on as I have been developing in node for the past 2 months. Coming from doing python and c# in the past, I picked up the asynchronous nature + promises and their "gotchas" within a few days of writing and rewriting an activemq module. All of our other requirements/stories have been developed at such a high speed relative to my past projects. Combined with docker and a QA team that writes automated tests with postman and protractor, our continuous integration is at a high maturity level.
