Angular.js: Combining $index and orderBy filter

When creating an application with Angular.js, I was using the $index variable inside an ng-repeat to track the index of the current item. The problem was that the moment I start combining this with an orderBy filter, the $index value was no longer correct.

I worked around the issue by passing the item itself around instead of the index.  In my function I used the indexOf method of an array.

Anyone with a better solution?

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try!

Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
