Why most js frameworks relay on very simple examples while they promising the wonderland? I need an advanced sample than a classic todo to evaluate a framework. Something like does multiple async ajax calls, survives page reloads while juggling data / models, and gracefully handles the errors and/or initial states. An example close to a real world project would be much appreciated.
PS: If that matters, in my day time job I'm using Angular...
edit: fixed typo.
