This Node JS function takes input as signed 2's complement and any particular reason why it returns wrong number of '1' bits Explanation: The input binary string 11111111111111111111111111111101 has a total of thirty one '1' bits.

Here is function which should return the output as 31 whereas it returns 1

            var hammingWeight = function(n) {
                let count = 0;
                while (n !== 0) {
                  n = n & (n - 1);
                  count++;
                }
              
                return count;
              };

            console.log(hammingWeight(11111111111111111111111111111101))

Here is console output

            PS C:\VSB-PRO> node Fibo.js
            1

any reason what could have gone wrong in the javascript code,your help is highly appreciated
