Understanding how to use Mulberry32 to achieve deterministic randomness in JavaScript

This technical article details the implementation and use of the Mulberry32 algorithm, a deterministic pseudo-random number generator (PRNG) in JavaScript. It explains why seeded randomness is crucial for reproducibility in debugging, simulations, and game development, contrasting it with Math.random(). The piece includes a code example and a breakdown of how the algorithm's bitwise operations and constants ensure a reliable, non-repeating sequence of numbers.
