In my view (!) it depends on the overall architecture of your app. In general it is regarded as best practice in traditional web solutions to keep the amount of logic in javascript to a minimum, and only use javascript to update the view with layout changes and such.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
