In my previous post on Rich Object Models and Angular.js
I introduced a simple strategy for setting up rich object-models in Angular.js. It turns out that once we've introduced the notion of a rich object-model, a number of more advanced object-oriented programming techniques become easy to implement. The first of these that I'm going to discuss is identity maps.
In this post I'm going to talk about what an identity map is, why you might need one, and I'll introduce a simple identity map implementation for Angular.js. I'm going to assume you've already read my foundational post
. If you'd like to see the portion of my talk at ng-conf devoted to identity maps, jump to the video
