JavaScript, Forgive me for posting it here

I know this is not a JavaScript group. Direct me to the right place if you
get offended

Question:

Does anyone know exactly what does code below mean or do.

var AZ = Function.AZ = function(someVar){...}

Thanks,

A function in JavaScript is an object, the reference to a function can
be stored in a variable. The code above creates a function and stores a
reference to it in the local AZ variable, and also one in Function.AZ.
Function is an existing class, and in JavaScript, you can add properties
to existing classes dynamically.

After this code is executed, you can call the function by calling

AZ( someVar );

or

Function.AZ( someVar );
