JavaScript(JS) JS find factorial of number using recursion

In JavaScript, you can find the factorial of a number using recursion. Here's an example:

function factorial(num) {
  if (num === 0 || num === 1) {
    return 1;
  } else {
    return num * factorial(num - 1);
  }
}

console.log(factorial(5)); // Output: 120

In the above example, we define a function called factorial that takes a number num as its argument. If num is equal to 0 or 1, the function returns 1. Otherwise, the function returns num multiplied by the result of calling factorial(num - 1). This recursive call continues until num is equal to 0 or 1, at which point the function returns 1.

We then call the factorial function with an argument of 5, which calculates the factorial of 5 using recursion and returns the value 120. You can replace the value of the argument with any other number to calculate its factorial using recursion.
