Question

This question has been striking me for many days…

Let’s say I have a very simple Backbone app with a list of items. When you click on an item, you see a detailed view of this item.

Is it better to

• create just ONE DetailedView and reuse it when the user clicks on the
  different items ; OR
• create one new DetailedView at each click ?

I prefer option 2, but there issues because I don’t destroy the views properly, and get the infamous “ghost views” problem with events firing from nowhere !

What is the best practice ?

Answer 1

I re-use views in similar circumstances. Just reuse DetailedView. That way:

• no need to create a structure to track all the views (since you wouldn’t want to duplicate an already created view.)
• No need to worry about memory size expanding without limit through long usage of the webapp
