RxJS: Removing fields from an object

Vote count: 0

Lets say I have an object with 4 fields like this:

obj = {a:"3", b:"7", c:"10", d:"123"}

and I need to 'narrow' it to an object with fewer fields, like that:

newObj = {a:"3", c:"10"}

I know this can be done by deleting the fields (ie. delete obj.b )

My question is, can this be done with RxJS? And if yes, how???

Thanks a lot!
