What are the potential pitfalls of using the_terms() function in PHP within Wordpress?

Using the_terms() function in PHP within Wordpress can potentially lead to performance issues, as it can result in multiple database queries being executed for each term. To avoid this pitfall, it is recommended to use get_the_terms() function instead, which retrieves the terms for a specific post without causing additional queries. 

$terms = get_the_terms( $post->ID, 'taxonomy_name' );
if ( $terms && ! is_wp_error( $terms ) ) {
    foreach ( $terms as $term ) {
        // Do something with each term
    }
}
