### What it does

Prefer `import.meta.{dirname,filename}` over legacy
techniques for getting file paths.

### Why is this bad?

Starting with Node.js 20.11, `import.meta.dirname` and `import.meta.filename`
have been introduced in ES modules.
`import.meta.filename` is equivalent to `url.fileURLToPath(import.meta.url)`.
`import.meta.dirname` is equivalent to `path.dirname(import.meta.filename)`.
This rule replaces legacy patterns with `import.meta.dirname` and `import.meta.filename`.

### Examples

Examples of **incorrect** code for this rule:

```js
import path from "node:path";
import { fileURLToPath } from "url";

const filename = fileURLToPath(import.meta.url);
const dirname = path.dirname(fileURLToPath(import.meta.url));
const dirname = path.dirname(import.meta.filename);
const dirname = fileURLToPath(new URL(".", import.meta.url));
```

Examples of **correct** code for this rule:

```js
const filename = import.meta.filename;
const dirname = import.meta.dirname;
```

## How to use

## Version
