10,775 PointsI noticed the counter variable has a global scope and is being referenced inside the function. Is that the best practice
Should you set the variable within the function and then update the variable with counter += inside as well?

Treehouse TeacherThe while statement doesn't have scope in JavaScript. Other languages have block scope but JavaScript doesn't. So a variable declared inside a while loop is in global scope as well.

Treehouse TeacherOr to be more accurate -- a variable declared inside a while loop is in the same scope as the while loop itself. For example, if the while loop is inside a function, then the scope of the while loop is the function. If the while loop isn't inside a function, its scope is the global scope.
