# or

## Usage

### `defineConfig()`

The `defineConfig()` function allows you to specify an ESLint configuration with full type checking and additional capabilities, such as `extends`. Here's an example:

```js
// eslint.config.js
import { defineConfig } from "@eslint/config-helpers";
import js from "@eslint/js";

export default defineConfig([
	{
		files: ["src/**/*.js"],
		plugins: { js },
		extends: ["js/recommended"],
		rules: {
			"no-var": "error",
			"prefer-const": "error",
		},
	},
	{
		files: ["test/**/*.js"],
		rules: {
			"no-console": "off",
		},
	},
]);
```

### `globalIgnores()`

The `globalIgnores()` function allows you to specify patterns for files and directories that should be globally ignored by ESLint. This is useful for excluding files that you don't want to lint, such as build directories or third-party libraries. Here's an example:

```js
// eslint.config.js
import { defineConfig, globalIgnores } from "@eslint/config-helpers";

export default defineConfig([
	{
		files: ["src/**/*.js"],
		rules: {
			"no-var": "error",
			"prefer-const": "error",
		},
	},
	globalIgnores(["node_modules/", "dist/", "coverage/"]),
]);
```
