Answer 1

static properties appear on the Class objects. They do not appear on instances of the class.

They are intended to hold static methods.

From MDN:

The static keyword defines a static method for a class. Static methods aren't called on instances of the class. Instead, they're called on the class itself. These are often utility functions, such as functions to create or clone objects.
