When importing builtin modules, it's better to use the [`node:` protocol](https://nodejs.org/api/esm.html#node-imports) as it makes it perfectly clear that the package is a Node.js builtin module.

Note that Node.js support for this feature began in:

> v16.0.0, v14.18.0 (`require()`)
>
> v14.13.1, v12.20.0 (`import`)

## Fail

```

## Pass

```js
import dgram from 'node:dgram';
```

```js
export {strict as default} from 'node:assert';

```js
import fs from 'node:fs/promises';
```

```js
const fs = require('fs');
```
