Minor issue: Update comment URL (point to secure page https:)
I am trying to eliminate http: wherever I can, and replace it with https:.
In cloud.js
there is a comment that refers to http://ejohn.org/blog/nodename-case-sensitivity/. The page immediately redirects to a new (and secure) page: https://johnresig.com/blog/nodename-case-sensitivity/
So, a quick fix to the comment would be all that's needed.
