@std/random

Unstable

This @std package is experimental and its API may change without a major version bump.

Overview

Utilities for generating random numbers.

Example of generating a random integer with fixed seed number:

import { randomIntegerBetween } from "@std/random";
import { randomSeeded } from "@std/random";
import { assertEquals } from "@std/assert";

const prng = randomSeeded(1n);

assertEquals(randomIntegerBetween(1, 10, { prng }), 3);

Example of generating a random integer between two values:

import { randomIntegerBetween } from "@std/random";
import { randomSeeded } from "@std/random";

const prng = randomSeeded(BigInt(crypto.getRandomValues(new Uint32Array(1))[0]!));

const randomInteger = randomIntegerBetween(1, 10, { prng });
