How to use GlideAjax and Client Scripts with Best Practice in mind

I've seen a couple of questions in the community about how to get more data from the server when you write a Client Script. What comes in mind is everything from GlideRecord calls, use of getReference method to GlideAjax and g_scratchpad method.

 I made a video with having best practice in mind and that would rule out both the GlideRecord call and the getReference. I also show how to avoid another server call when you do a setValue on a reference field which is pretty common to do if your mind might be somewhere else when you write the code.

And you want an update set with the code that is used in the video, you can find it here:https://github.com/goranlundqvist/Update-sets#glideajax-example?
