Is There An Equivalent To RxJs<=4#ofArrayChanges In RxJs5

I am using Angular2 and I want to track changes in array,but there is only RxJs5,and seems it hasn`t such functionality.

Solution 1:

There is no equivalent. The Object.observe proposal has been withdrawn from ES7, so there is little point in having ofArrayChanges or ofObjectChanges in RxJS 5.
