wp_register_script() — Registers a new script. Registers a script to be enqueued later using the wp_enqueue_script() function.

Inputs: $handle (string): Name of the script. Should be unique. $src (string|false): Full URL of the script, or path of the script relative to the WordPress root directory.

Default empty array. $ver (string|bool|null): Optional. String specifying script version number, if it has one, which is added to the URL as a query string for cache busting purposes.
