Simple walkthrough of installing node, npm and express, and creating a simple server that returns "Hello World" for a get request to a url

Should this continue on the node page (https://starthacking.org/mac/node/) or start a new page?

@Monique2in are you interested in taking this on? There's a few tutorials on the Other page, but it would be great to vet them, update with any other tutorials you think are good, and put them on their own page like https://starthacking.org/web/ruby.
