/* 

    LeetCode Task:
    Given an integer n, return a counter function. This counter function initially returns n 
    and then returns 1 more than the previous value every subsequent time it is called (n, n + 1, n + 2, etc).

    // Increment Then Return
    // const createCounter = function(n) {
    //     let currentCount = n - 1;

    //         currentCount += 1;
    //         return currentCount;

    // Postfix Increment Syntax
