Maximum update depth exceeded in react native. I’m trying to count how many times map function (loop) executing but it gives this error

I’m trying to count how many times map function (loop) executing?
but it gives this error:

Maximum update depth exceeded. This can happen when a component
repeatedly calls setState inside componentWillUpdate or
componentDidUpdate. React limits the number of nested updates to
prevent infinite loops.

counterFun = () => {
        const { Counter } = this.state;
        this.setState({ Counter: Counter + 1 })
};

something.map((item)=>{
    return(
       this.counterFun();
    )
})

How can I count through map function OR any loop?

Thank you.
