Scripts !  To interact with SharePoint  

This set of scripts provide a nice template for interacting with SharePoint lists. In this example - I'm adding and pulling information from a Calendar (also a SP list). 
These scripts were also used with a Slack Hubot, so that the information can be added/pulled from a SmartPhone, tablet, etc.  (it's really nice to be able to add "Steve is Out of the Office today" to our team Calendar - right from my phone! ).    
Most browsers will allow you to download the files directly by clicking on the link. If not, right-click and open in new window.
