forms

Description

They need to provide a solution for the deletion of one index to another specific index.
i.e. I have a 100 elements in Reactive Form Array, and I need to remove 30 to 60 index elements. I need to handle this in for loop.
As you already provided us removeAt(), then it will be very helpful to provide this feature.

Proposed solution

FormArray.removeSplice(start, end);
something like that.

Alternatives considered
