Step-by-Step Calculation & Explanation

The factorial of a non-negative integer \( n \) is the product of all positive integers less than or equal to \( n \). It is used heavily in probability, combinations, and permutations. JavaScript's BigInt support enables calculating exact, high-precision results for factorials of large numbers without scientific notation.
