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

## Overview

<p>Utilities for generating random numbers.</p>
<p>Example of generating a random integer with fixed seed number:</p>

```js
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);
```

<p>Example of generating a random integer between two values:</p>

```js
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 });
```

### Add to your project

```sh
deno add jsr:@std/random
```
