In both cases we use this two lines

```
      let currCount = countRef.current;
      setCounter(currCount => currCount + 1);
```

why we use the same name for the function parameter inside the setCounter?

setCounter(**currCount** \=> currCount + 1);

I believed that adding an arrow function inside a setState will make the parameter the last value of the state thus unrelated with the countRef.current, and unrelated with the currCount, which is a local function variable.
