JMeter: How to access loop counter inside ForEach Controller?

I have a ForEach controller in JMeter.

How can I access counter of a loop inside this controller (through variable) and then use it for creating new variables?

No need for a counter.

The loop index is built into JMeter 4.0 and later - see Jmeter/Groovy: getting iteration number without reference to Beanshell

Jmeter bug 61802 - Loop / ForEach Controller should expose a variable for current iteration

For example if your ForEachController is named ForEachCard then this will get you the loop index (starting at zero).

def cardIndex = Integer.parseInt(vars.get("__jm__ForEachCard__idx"));

This would get you the ordinal and then obtain the associated value from a previous JSON Extractor using capture all ( Match# = -1 )

def cardOrdinal = Integer.parseInt(vars.get("__jm__ForEachCard__idx")) + 1;
def currCardBalance = vars.get("cardBalance_" + cardOrdinal )

I have used this ForEach controller in my script and I got the answer. First create a regular expression for the value you are looking for and then add a ForEach controller

With the above image you will get a clear idea about it.

Put Counter configuration element inside ForEach Controller and check attributes "Track Counter Independently for each User" and "Reset counter on each Thread Group Iteration"
