Number of 1 Bits

Write a function that takes an unsigned integer and returns the number of ' 1 ' bits it has (also known as the Hamming weigh T).

For example, the 32-bit integer ' One ' 00000000000000000000000000001011 has a binary representation, so the function should return 3.

/**/varfunction(n    ) {var res = 0;      for (i = n; I!== 0;) {        if(i% 2 = = 1) {            res+ +;        }         = parseint (I/2);    }     return Res;};
