With its package manager, npm, containing more than 350.000 tools, the community of JavaScript developers and the number of resources grows exponentially.

Node.js has been adopted by big corporates like Microsoft, IBM, Paypal and SAP. Startups as big as Trello, Uber and Medium use it as a foundation for their platforms.

Node.js is not the best choice if you need fast development. The Rails approach allows us to be more agile & to reduce the time-to-market.
