This example demonstrates a minimalist MVC architecture built with Cranium, a custom library that uses Underscore.js for utility functions and jQuery-like DOM selection. It shows how a model, view, and controller interact: user clicks on increment or alert buttons trigger controller methods, which update the model, and the view re-renders an Underscore template displaying the counter value. A separate todo example illustrates model changes notifying the view to re-render its checkbox and title template. The code relies on Cranium’s Events system for model-view communication and DOM event binding.
