/*
The this keyword refers to different objects depending on how it is used:
-In an object method, this refers to the object.
-Alone, this refers to the global object.
-In a function, this refers to the global object.
-In a function, in strict mode, this is undefined.
-In an event, this refers to the element that received the event.
-Methods like call(), apply(), and bind() can refer this to any object.

----------------------------------------------------------------------------------------------------
The apply() method can be used to invoke (call) a method with an owner object as an argument (parameter).
The apply() method takes arguments as an array.
----------------------------------------------------------------------------------------------------

The difference is:

The call() method takes arguments separately.
The apply() method takes arguments as an array.
