 *** Node.js, Cloud9, and BoneSccript
-The BeagleBoard.org Linux distribution comes complete with a set of technologies that you can use to quickly get started with developing software and hardware applications on the boards. These are called Node.js, Cloud9, and BoneScript. *Node.js* is a programming language, *Cloud9* is an online software integrated development environment (IDE) in which you can write *Node.js* code, and *BoneScript* is a library of code for Node.js that allows you to interact with Beagle board hardware[Molloy@2019].
