Day 89: Factorial Using Recursion of 100DaysCodingChallenge

Hello all, 

#day89 

Day89 

Today's my task was to Write a Program to Find Factorial of a given number N using Recursion. (N is entered by the user).

I have started the 100 days of coding challenge to improve my programming skills..

Code : 

//let a = prompt("Enter a Number : ");
// program to find the factorial of a number
function factorial(x) {
  // if number is 0
  if (x == 0) {
    return 1;
  }
  // if number is positive
  else {
    return x * factorial(x - 1);
  }
}
// take input from the user
const num = prompt('Enter a positive Number: ');
// calling factorial() if num is positive
if (num >= 0) {
  const result = factorial(num);
  console.log(`The Factorial of ${num} is ${result}`);
}
else {
  console.log('Enter a positive Number.');
}
function factorial1(n) {
  if (n >= 1) {
    return n * factorial(n - 1);
  }
}
//console.log(factorial(parseInt(a)));

Output :     

 

Happy Coding:)
