Filter by null value

[matthews90]

Cannot filter array by property null value. I cant find objects with null property value:

So you expect that pipe will return only one value { name: null }?

Yes, please.

My Use-Case for this is, having an array of elements where I want to filter:

Give me every element
Where the value is "Group1" or "Group2" or where property is empty

Only if the element has the value "Group3", it should be filtered out.
