jQuery does not work

Scripts and stylesheets should always be loaded in the head or in the footer via the wp_enqueue_scripts action hook. wp_enqueue_scripts is the proper hook to use when enqueuing items that are meant to appear on the front end

The init hook executes before wp_head which is to early for script to load in the header. The wp_enqueue_scripts action hook is executed right after wp_head, allowing scripts and styles to be loaded properly. This also have the benefit of naming script dependencies and ordering scripts and styles to load properly
