Version: 1.0.0
Runtime: JavaScript · Node.js 22 / modern browsers
Verification: Usage lines executed in Node.js 22 and headless Chromium; no external services

## Implementation

```javascript
function randomIntegers(min, max, count) { return Array.from({ length: count }, () => Math.floor(Math.random() * (max - min + 1)) + min); }
```

## Usage

```javascript
const values = randomIntegers(1, 100, 10);
values.length; // → 10
values.every(n => Number.isInteger(n) && n >= 1 && n <= 100); // → true
```

Lines marked → were executed in Node.js 22 and in headless Chromium, and each result was compared with the value shown. Lines marked e.g. are illustrative.

## Limits

- Values can repeat. For distinct values, shuffle a range and take the first count, as in Get random items of an array.

The function does not validate its arguments. Add checks where it receives untrusted input.
