In this article, we are calculating the factorial of a number using JavaScript. Here, we are using two ways to find the factorial. The first one is the iterative approach, and another one is the recursive approach. Here, we are iterating a loop over the sequence of numbers to get the factorial of a given number. Using this approach, the consumption of memory is less than the recursive implementation.

But the code is lengthier than the recursive method. In this example, there is a text field that requires a number and a button, which gives us the factorial of the entered number.

We have to enter a number in the given textfield to find the factorial of that number. Then we need to click the given button named Factorial to get the result. If we enter a negative number, then the program calculates the factorial of 0 , which is 1. In this approach, we are using recursion to calculate the factorial of a number. Here, we call same function again and again to get the factorial. Using recursion, we have to code less than the iterative approach. Here there is a function fact , which accepts a parameter num.

It is a number for which we need to calculate the factorial. Java Comparators. Collection Algorithms. Java Collection Algorithms. Java Read-only Collections And Algorithms. Java Singleton. Java nCopies Collections - Collections.
