crypto‑random provides a zero‑dependency, cryptographically secure random number generator that can be used as a drop‑in replacement for `Math.random` in both Node.js (v14+) and modern browsers. It exposes simple methods like `value()` for a random float [0, 1) and `range(min, max)` for secure integer selections, making it useful for developers who need stronger randomness without changing their existing code.
