The first parameter to wp_enqueue_script()—in this case, dashboard—is the handle of the script. The handle can be pre-registered using wp_register_script(), and that’s where the script’s path will be set.
dashboard isn’t one of the default scripts that WordPress registers, but it’s entirely possible some other entity has registered it.
