Can someone explain how this works? Thanks!

ProcessData( DataArray )
{

TheData = DataArray || [];
...
}

ProcessData(["Item1", "Item2", "Item3", "Item4"]);

That's a syntax error. It should be:

function ProcessData( DataArray)

Or:

myVar = ProcessDate( DataArray)

> {
>
> TheData = DataArray || [];

It checks to see if DataArray is an array. If it is, it sets TheData =
to that array. If not, it sets TheData to an empty array.
