Minimising duplication using ((){})();

[Andrew Poulos]

I'm building some code that using this type of structure to interface to
SCORM compliant LMS:

var API = (function() {
// Private variables
var started = false;

// Private methods

// Public methods
return {
// Initialise
Initialize : function() {
started = true;

}
}
})();


Unfortunately there are two common standards that need to be satisfied
and I was hoping to do it with minimal duplication.

My problems are these:

1. Some LMS will be referring to 'API' and some will be expecting the
name 'API_1484_11'. If I add this line

var API_1484_11 = API;

does that mean, say, that I could call API.Initialize( ) and it would be
the same as calling API_1484_11.Ini tialize()?

2. The public methods are identical in content but need to have slightly
different names for 'API' and 'API_1484_11'. For example, 'Initialize'
and 'LMSInitialize' . How can I achieve this without duplicating the
entire method?

Yes. They not only behave the same, they are the same: The same method
called on the same object.

2. The public methods are identical in content but need to have
slightly different names for 'API' and 'API_1484_11'. For example,
'Initialize' and 'LMSInitialize' . How can I achieve this without
duplicating the entire method?

API.LMSInitiali ze = API.Initialize;
var API_1484_11 = API;

API.Initialize( );
API_1484_11.LMS Initialize(); // exactly the same

.... as long as you don't have the same method name meaning different
things in the different APIs.
