High Level Goals

1. To generate high quality qualified sales leads.
2. To be effective developers because we know and can fix big chunks of the stack.
3. To give our developers a fun outlet for creativity.

Focus on "simpler and more scalable state management"

I think it's in Bitovi's best interests to start out pursuing the following mission and identity:

This just tries to demostrate the fact that because attr1 is supplied by props, even though the viewModels property keeps getting set, it just keeps going back to the props value because of the current implementation. To run the demo:

• clone this repo (a gist is a repo)
• run npm install (or npm i if you're nasty)
• run npm start and checkout http://localhost:3000/
