How to get index in a pagelist during iteration

Background: 

While iterating in a pagelist

Example : EmployeeList

To refer to page at that point: we use EmployeeList(<CURRENT> )

But how to get the index if we have to write some condition, like at index= nth position => achieve some logic.

Answer : pxListSubscript

Pega provides one property called pxListSubscript which is declaratively calculated and kept at each page level in a pagelist.

We can use it instead of setting  a property and using it for same purpose. 

Feel free to share if you have any other approaches.
