Javascript–Using splice instead of delete

I have to admit that the amount of Javascript code I write is really limited. And even then I use TypeScript most of the time. Anyway this is only a disclaimer because maybe I'm stating something that is obvious to you. It certainly wasn't to me :-)!

I had a really simple use case to solve: I needed to delete a specific item from an array .I didn’t know the exact function name anymore so I asked Google and got back with the delete operator.

This turns out to the wrong approach as the delete operation will delete a property from an object and set it to undefined:

The correct way is to use the splice function:

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...
