value of this function can be passed to [`linter`](https://codemirror.net/6/docs/ref/#lint.linter)
|
||||
to create a JavaScript linting extension.
|
||||
|
||||
Note that ESLint targets node, and is tricky to run in the
|
||||
browser. The
|
||||
[eslint-linter-browserify](https://github.com/UziTech/eslint-linter-browserify)
|
||||
package may help with that (see
|
||||
[example](https://github.com/UziTech/eslint-linter-browserify/blob/master/example/script.js)).
