## Install

This package is [pure ESM](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c). If you're not ready yet, install an older version of this program, 4.1.0 (`npm i ranges-invert@4.1.0`).

```bash
npm i ranges-invert
```

## Quick Take

```js
import { strict as assert } from "assert";

import { rInvert } from "ranges-invert";

assert.deepEqual(
  rInvert(
    [
      [3, 5],
      [5, 7],
    ],
    9, // string length needed to set the boundary
  ),
  [
    [0, 3],
    [7, 9],
  ],
);
```
