Description

Devuelve el factorial del entero proporcionado. Si el entero se representa con la letra n, un factorial es el producto de todos los enteros positivos menores o iguales a n. factoriales a menudo se representan con la notación abreviada n! Por ejemplo: 5! = 1 * 2 * 3 * 4 * 5 = 120 Solo se proporcionarán a la función números enteros mayores o iguales a cero. Recuerda usar Read-Search-Ask si te atascas. Escribe tu propio código.

Challenge Seed

function factorialize(num) {
  return num;
}

factorialize(5);

Solution

function factorialize(num) {
  return num < 1 ? 1 : num * factorialize(num - 1);
}

factorialize(5);
