JavaScript - Number of 0 bits in a binary representation

JavaScript Bit Manipulation: Exercise-3 with Solution

Write a JavaScript program to count 0 bits in the binary representation of a given integer.

Test Data:
(45) -> 2
(17) -> 3
(15) -> "Parameter value is not an Integer!"

Sample Solution:

JavaScript Code:

function Binary_Count_SetBits(a) 
{
  // check whether input is an integer
  if (!Number.isInteger(a))
    {
      return('Parameter value is not an Integer!')
    }
    return a.toString(2).split('0').length - 1
}
console.log(Binary_Count_SetBits(45))
console.log(Binary_Count_SetBits(17))
console.log(Binary_Count_SetBits("15"))

Sample Output:

2
3
Parameter value is not an Integer!
