_e( 'Sorry, page not found.', 'treehouse-portfolio' );

In the video, the code is: _e( 'Sorry, page not found.' ); but in the final-theme version I see: _e( 'Sorry, page not found.', 'treehouse-portfolio' );

Why is the meaning of the second argument(parameter)? I have seen this quite a bit in other themes.

Hi Marie,

The second parameter is optional. As far as I can honestly tell, its only helpful for translated text.

Mark is right, it's optional and it's for translating text using WP's system to do so. One other link I'll provide, it's quite dry, but it's official, is here: https://codex.wordpress.org/I18n_for_WordPress_Developers
