Differences between register_nav_menu( 'primary-menu', 'Primary Menu' ); and 'primary-menu' => __( 'Primary Menu', 'h)?

whats a different between these two? I cant wrap my head around it just yet.

If you are looking at the codex and wondering why there is

<?php register_nav_menu( $location, $description ); ?>

and

<?php register_nav_menus( array( $location => $description ) ); ?>

The difference between the two is whether you want to have more than one menu. They are different functions that handle their arguments differently. The first function takes two arguments that are equivalent to the key value pair for the first menu element in the array and is only going to work for one menu. The second function can accept multiple menus as key value pairs.

I came across this question while trying to figure out what the double underscores mean before __( 'Primary Menu'). It turns out that it has to do with translating text. If you are interested, here is what WordPress has to say about it

Thank you Erika Nielsen! I don't think I would have found the information about

 __( 'Primary Menu')

without this comment. Also, Had you posted your answer in the answer section instead of the comments, I could have given you a +1 :-)

Thank you so much for your answer Erika Nielsen !!! I was starting to pull my hairs out Googling __() to no avail. I would never have thought it has something to do with internationalisation / translation of text. Great to know !
