Write a function charFreq() that takes a string and builds a frequency listing of the characters contained in it. Represent the frequency listing as a Javascript object. Try it with something like charFreq("abbabcbdbabdbdbabababcbcbab").



            charFreq("abbabcbdbabdbdbabababcbcbab");


        //find frequency of characters in string
        function charFreq(string)
        {
            var obj = new Object();
            var occurences = 0;
            var letter = '';
            for(var i = 0; i < string.length; i++)
            {
                 letter = string[i];

                for(var j = i+1; j<string.length; j++)
                {

                    if(string[i] == string[j])
                    {
                        occurences++;
                    }
                }
                obj[i] = new Object();
                obj[i].chars = letter;
                obj[i].occ = ++occurences;
                occurences = 0;
            }
            console.log(obj);
        }
