## Usage

```javascript
import {EditorView, basicSetup} from "codemirror"

it will return <code>{path: [], name: &quot;x&quot;}</code>. When not in a property or
name, it will return null if <code>context.explicit</code> is false, and
<code>{path: [], name: &quot;&quot;}</code> otherwise.</p>

<dd><p>Connects an <a href="https://eslint.org/">ESLint</a> linter to CodeMirror's
<a href="https://codemirror.net/docs/ref/#lint">lint</a> integration. <code>eslint</code> should be an instance of the
<a href="https://eslint.org/docs/developer-guide/nodejs-api#linter"><code>Linter</code></a>
class, and <code>config</code> an optional ESLint configuration. The return
value of this function can be passed to <a href="https://codemirror.net/docs/ref/#lint.linter"><code>linter</code></a>
to create a JavaScript linting extension.</p>
<p>Note that ESLint targets node, and is tricky to run in the
browser. The
<a href="https://github.com/UziTech/eslint-linter-browserify">eslint-linter-browserify</a>
package may help with that (see
<a href="https://github.com/UziTech/eslint-linter-browserify/blob/master/example/script.js">example</a>).</p>
