Question

In this:

somefunction = function() {

    somefunction.method = function() {
         //stuff
    }
//other stuff
}

Is somefunction executed everytime somefunction.method is?

Answer 1

No, somefunction is executed when you have any of these lines:

somefunction()
somefunction.call()
somefunction.apply()
new somefunction;

somefunction.method() will only execute somefunction.method, but that will have access to variables in the scope of somefunction (as well as its own local variables and all global variables of course).
