How to use For Loop in modified java script Plugin

How to use for loop in modified javascript Plugin (when we used for loop it returns only last value.
For Ex.
for(var i = 0;i<5;i++)
It returns 5th value only.

In Process Studio modified java script step will be executed for every row & for no of iterations specified in loop and it will return last iteration value. If you want to check/assign every iteration value then use start loop & continue loop step instead of modified java script.
