`require_glob()` can recursively load `.js` files, optionally non-recursive as well.
Possible parameters are:
- Path as string, where you would like to start including files. Mandatory. Pattern matching possible, see [GoLand path/filepath/#Match docs](https://golang.org/pkg/path/filepath/#Match).
- If being recursive. This is a boolean if the search should be recursive or not. Define either `true` or `false`. Default is `true`.
