ToDoMVC is project that implements a simple Web App in multiple JavaScript web frameworks. I believe this is an admiral idea. The purpose is to let you the programmer to see how the different frameworks can be used to decide between the many available.
MVC is Model-View-Controller Pattern when an application is divided into a Model of the solution domain, a View or display of the model and the Controller that contains the logic to update the model. I associated MVC with Smalltalk-80 design and the Wikip article relates MVC back to Xerox-PARC and Smalltalk or the "momma of object programming."
