Why did Zac globalize the variable $page in the first example function named custom_wp_title? I can't figure this out why he puts global $page in the function as he never does anything with $page after he globalizes it. Would the function still work without it or am I missing something? Thanks!

and is_front_page()
use the $page
information.
Since he create new function, is_home()
and is_font_page()
can't access the $page
info unless you globalize it in the function.
I can't find the documentation for this issue so I'm not 100% sure. Please correct me if I am wrong.
