factorial of a number

Question

I have the following code but it is not giving perfect result for factorial can u find it out plz

Answer 1

function fact(n) {
  if (n > 1) {
    return n * fact(n-1);
  } else {
    return 1;
  }
}
console.log(fact(5));

Using ternary operator we replace the above code in a single line of code as below

function fact(n) {
      return (n != 1) ? n * fact(n - 1) : 1;
 }
console.log(fact(5));
