Comment:

 Hi @alex0902 - Welcome to WordPress Trac!
 WordPress ships with a polyfill for the `is_countable` function that PHP
 7.3 natively provides. This means all WordPress users, regardless of the
 PHP version, can now use the `is_countable()` function.

 Although arrays are the most common thing that we call `count()` on, it's
 not the only data type. Any objects whose class implements `\Countable`
 interface are countable.

 If you would like to get to the code contributions to WordPress, this
 could be a good one to get started with!
