Great way to learn to code JavaScript on mobile

I have been wanting to learn to code via mobile and this is the first solution I have stuck to all the way through. It works offline so I can use during my commute in the subway and is fun. Its an engaging way to learn JavaScript and I would recommend it to anyone who is a business person looking to understand the fundamentals like me.
