2. Data helpers: This will cover some of the useful functions for manipulating, getting, and returning data, such as __return_[true|false|zero|empty_array|null](), wp_list_pluck(), wp_list_filter(), [add|remove]_query_arg(), absint(), form_option(), url_to_post_id(), trailingslashit(), etc.
3. Action helpers: This will cover some of the useful functions for executing functionality, such as: media_sideload_image(), wp_remote_[get|post](), wp_localize_script(), wp_mkdir_p(), get_temp_dir(), wp_die(), etc.
