The number of modules don't matter, but what does matter is that NVM and NPM are incredible tools. I've never used any package or version manager that comes close to their polish, ease of use, and simplicity. They make a huge difference. I think the true success story of node.js lies in those tools. The deployment and project building process is not just easy, it's actually enjoyable, and exciting. I cannot say that about any other build tool. I do think having the templating portion of the web stack being in a client side language is important, as there's typically lots of overlap and interoperability that can happen at that layer between the client and server. As for the rest, I don't buy into the whole having a single language is better for understanding and hiring. Picking the right language that has the right metaphors for the problem will make things easier than having the same language everywhere.
