Plone 5 will introduce some new concepts, for some, with working with Java Script in Plone.

Further a base class for writing upgrade steps with a variety of helpers for common tasks is provided.

This document covers the procedures and issues involved in upgrading an existing Plone installation.
We chose AMD over other module loading implementations(like commonjs) because AMD can be used in non-compiled form in the browser.
