Just to Update on the ‘return’ statement, it returns ‘integer’ for individual ‘menu-location’ if no menu is assigned. To be precise, it returns an Array like so:
```
print_r(get_nav_menu_locations());
```
Returns an array like so
Array ( [main-menu] => 757 [mobile-menu] => 1506 [footer-menu] => 0 )
main-menu and mobile-menu are assigned so they return Menu ID whereas footer-menu is unassigned and thus returns ‘0’.
