wp_print_scripts( string|bool|array $handles = false )

Prints scripts in document head that are in the $handles queue.

Description Description

Called by admin-header.php and ‘wp_head’ hook. Since it is called by wp_head on every page load, the function does not instantiate the WP_Scripts object unless script names are explicitly passed. Makes use of already-instantiated $wp_scripts global if present. Use provided ‘wp_print_scripts’ hook to register/enqueue new scripts.
