best practice about php code

Hi

I am far away from being a developper, so I was wondering if this code is a good way to include html into my front-page.php or if I should use “echo”, or something else better.

My worry is to have something light and as fast as possible, that’s the reason why I avoid as much as I can to insert widget area with widget inside. But maybe it is a bad thing !

Thank you to anybody who have something to say about this !

remove_action( 'genesis_loop', 'genesis_do_loop' );
add_action( 'genesis_loop', 'one_pager_homepage_content' );
