Enqueue scripts and styles properly using wp_enqueue_script() and wp_enqueue_style() with appropriate dependencies and versions. Use wp_localize_script() to pass PHP data to JavaScript. Avoid inline styles and scripts; always enqueue them separately. Define proper dependencies like jquery or wp-i18n. Conditionally enqueue resources on specific pages to reduce loading time. Use asset files generated by build tools for better organization. Minify production assets. Test your frontend code across browsers. Proper enqueuing prevents conflicts with other plugins and themes. Following WordPress enqueuing standards ensures compatibility and performance.
