Yes. If a person already knows JavaScript well, then it will be easier for them to write a CLI app/utility/script in JS than it would be to write a shell scrip

    Look at the top 2 depended on modules modules in the entire of the server side node.js ecosystem and guess what they were written for - https://npmjs.org/ https://npmjs.org/ I wrote a database specifically for web browsers and someone case along and write a relatively small pull request and it now works in node / on the server / with a http api - http://pouchdb.com http://pouchdb.com

    I actually reuse the same code a lot, which is a very nice feature once you get used to it. I share code between the client and server. For example, I have data type checks where I reuse the same library and the same application specific code on both the client and server. I expose substantial portions of my server-side code via the command line. I also frequently call shell scripts from node as there are certain things I find easier to write in a shell script. That said, I don't know if this amount of reuse is typical. And, code reuse is clearly not the only consideration.
