Day2 : Counter

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).

var createCounter = function(n) {
    
    return function() {
        return n++;
    };
};

Example 1:
Input:
n = 10
["call","call","call"]
Output: [10,11,12]

Example 2:
Input:
n = -2
["call","call","call","call","call"]
Output: [-2,-1,0,1,2]

開始覺得這個 js 30天挑戰有點瞧不起人...
希望後面會變難，不然我花在文章排版的時間，還比較多＝＝

var createCounter = function(n) {
    
    return function() {
        return n++;
    };
};
