I need to remove the following properties from the above mentioned JSON objects and the result of that should be compared:

I used underscore's _.omit () functionality it removed only the outer collection property but it failed to remove the inner collection property eg: PatientStatus.StatusId in the above JSON

I also tried using delete keyword of javascript it is working, but is there any better way to do it ?

Answer 1

Try to JSON.parse the string, and then delete the property you want to remove..
