The resources.Concat function returns a concatenated slice of resources, caching the result using the target path as its cache key. Each resource must have the same [media type].
Hugo publishes the resource to the target path when you call its [Publish], [Permalink], or [RelPermalink] method.
{{ $plugins := resources.Get "js/plugins.js" }}
{{ $global := resources.Get "js/global.js" }}
{{ $js := slice $plugins $global | resources.Concat "js/bundle.js" }}
