| AutoHotkey's ''class'' syntax is so-called [[https://en.wikipedia.org/wiki/Syntactic_sugar|sugar syntax]]. Sugar syntax is an easier to read and write shorthand for code that is too verbose to work with directly. The implication of calling class syntax as sugar syntax is that you can do almost everything that the ''class'' keyword does entirely without using it. There are a few minor exceptions that we will go over later. | AutoHotkey's ''class'' syntax is so-called [[https://en.wikipedia.org/wiki/Syntactic_sugar|sugar syntax]].

| Class syntax is used to simultaneously define two things: a "prototype object" and a "class object". A prototype object is used the *base* object for class instances. When you create an object like ''myObject := MyClass()'', the value of ''myObject'' ends up looking something like ''myObject := {base: MyClass.Prototype}''. The prototype object is the object that holds all the method functions that you can call on the class instance. | Class syntax is used to simultaneously define two things: a "prototype object" and a "class object".

| Remembering the fundamental of how functions stored in objects are called, it would mean that in this following example, when ''testMethod'' is called the value of ''this'' will be equal to ''myObject'' //not// ''MyClass.Prototype''. | Remembering the fundamental of how functions stored in objects are called, it would mean that in this following example, when ''testMethod'' is called the value of ''this'' will be equal to ''myObject'' //not// ''MyClass.Prototype''. |
