In this tutorial, we will learn how to calculate the factorial of an integer with JavaScript, using loops and recursion. Calculating Factorial Using Loops We can calculate factorials using both the while loop and the for loop. We'll generally just need a counter for the loop's termination and...
We'll try it with 4: Enter a number: 4 The result is: 24 You can use a calculator to verify the result: 4! is 4 * 3 * 2 * 1, which results 24. Now let's see how we can calculate factorial using the while loop. Here's our modified method: public static int getFactorial...
