Is it possible to modify a function itself when its property function is called?

Question

Basically I want to do this:

someFunction() // do something

someFunction.somePropertyFunction()

someFunction()  // Now someFunction is modified; it should now          


        

Answer 1

Easily. Here's an example:

var derp = 123;
someFunction = function() {alert(derp);};
someFunction.somePropertyFunction = function() {derp = 456;};

someFunction(); // alerts 123
someFunction.somePropertyFunction();
someFunction(); // alerts 456

Okay, that's an oversimplified example, but yeah, it's entirely possible.
