JavaScript Tutorial

The simplest way to calculate the factorial of a number is by using a for loop.

Factorial Program in JavaScript Using for Loop

Factorial is a mathematical operation that multiplies a number by all the positive integers less than itself. Represented as n!, it is a key concept in mathematics and is extensively used in combinatorics, algebra, probability, computer science, and algorithmic problem-solving. Factorial calculations are particularly important in understanding permutations, combinations, and various mathematical proofs. For example:
<ul>
<li dir="ltr" aria-level="1">
5! = 5 &times; 4 &times; 3 &times; 2 &times; 1 = 120
</li>
<li dir="ltr" aria-level="1">
0! = 1 (special case by convention)
</li>
</ul>
