8.1 Getting Angular up and running
Angular is the second JavaScript framework in the MEAN stack, with Express being the other. Express, as we’ve seen, sits on the server, whereas Angular sits on the client side in the browser.

The approach is very much in the MVC style, but Angular has been defined as an MVW framework, where the W stands for “whatever works for you.” Sometimes it might be controllers, or the view-model, or services. It depends on what you’re doing at any given point.
