Evil or Odious.js

// The number n is Evil if it has an even number of 1's in its binary representation.
// The first few Evil numbers: 3, 5, 6, 9, 10, 12, 15, 17, 18, 20

// The number n is Odious if it has an odd number of 1's in its binary representation.
// The first few Odious numbers: 1, 2, 4, 7, 8, 11, 13, 14, 16, 19

// You have to write a function that determine if a number is Evil of Odious, function should return "It's Evil!" in case of evil number and "It's Odious!" in case of odious number.

// good luck :)


//Notes:
//converting a numver to binary - .toString(2)
//checking is n is Number

function evil(n) {
    let binaryN = Number(n).toString(2).split('');
    let ones = 0;
    for(let i = 0; i < binaryN.length; i++) {
      if(binaryN[i] === '1') {ones++}
    }
    if(ones %2 === 0) {return `It\'s Evil!`}
    else return `It\'s Odious!`
