How to increment value each time when you run function with JavaScript?

To increment value each time when you run function with JavaScript, we can create a variable outside the function and increment that when the function is run.

For instance, we write:

let count = 0
const f = () => {
  count++
}
f()
f()
console.log(count)

to define the count variable.

Then we define function f that increments count by 1.

Then we call f twice.

As a result, count is 2 according to the console log.
