How is an object method called?

Unlike Array prototype methods like sort() and reverse() that are used on the array instance, Object methods are used directly on the Object constructor, and use the object instance as a parameter . This is known as a static method.

Calling an object’s method is similar to getting an object’s variable. To call an object’s method, simply append the method name to an object reference with an intervening ‘. ‘ (period), and provide any arguments to the method within enclosing parentheses .

You also use an object reference to invoke an object’s method. You append the method’s simple name to the object reference, with an intervening dot operator (.) . Also, you provide, within enclosing parentheses, any arguments to the method. If the method does not require any arguments, use empty parentheses.
