Private AccessPrivate Access
This function’s access is marked private. This means it is not intended for use by plugin or theme developers, only in other core functions. It is listed here for completeness. Use get_translations_for_domain() instead.
Loads plugin and theme textdomains just-in-time.
When a textdomain is encountered for the first time, we try to load the translation file from
wp-content/languages, removing the need to call load_plugin_texdomain() or load_theme_texdomain().
(string) (Required) Text domain. Unique identifier for retrieving translated strings.
(bool) True when the textdomain is successfully loaded, false otherwise.
