This package uses [micromatch](https://github.com/micromatch/micromatch) for glob patterns. JavaScript files can also export advanced configuration as a function.

-## Using JS configuration file
+## Using JS configuration files
 
 Writing the configuration file in JavaScript is the most powerful way to configure lint-staged (`lint-staged.config.js`, [similar](https://github.com/okonet/lint-staged/README.md#configuration), or passed via `--config`). From the configuration file, you can export either a single function or an object.
