I love and hate javascript. I set out to do a fully ajax/state driven form interface that operates with multiple interdependent data objects which all extend a base class.

React/Angular may have been a better call but I just didn't have time so I needed to rapid prototype in jquery /vanilla JS.

I'm in the midst of learning and refactoring all the ajax calls to promises and then to async/await, so it's a huge learning experience...

Meanwhile I've got to build objects to represent the data on the backend which is all legacy OScommerce/PHP

Hell of a ride.
