#19904 — Can somebody explain this short code

Note this code is autogenerated
What I don't understand is this
How is it possible to call function  dsFrsvoyage_ttFrsvoyage when the 
signature doesn't match.
The function  dsFrsvoyage_ttFrsvoyage doesn't any argument but you can call 
it with an argument.


function dsFrsvoyage()
{
    this.ttFrsvoyage = new Array(1);
    this.ttFrsvoyage[0] = new dsFrsvoyage_ttFrsvoyage(1);
}

function dsFrsvoyage_ttFrsvoyage()
{
    this.Vesselid = "";
    this.Arrtime = null;
    this.Deptime = null;
    this.Objecttype = "";
    this.Dnggoods = false;
    this.prevport = "";
    this.port = "";
    this.nextport = "";
    this.VoyNum = "";
    this.done = false;
    this.sent = "";
    this.todestination = "";
    this.fromdestination = "";
    this.Remark = "";
    this.errstat = "";
    this.cancelled = false;
    this.Sendstat = "";
    this.Objectid = 0;
    this.UID = "";
    this.UIDDATE = null;
    this.UIDTIME = "";
    this.UIDPGM = "";
    this.Z_Seq = 0;
    this.MISC1 = "";
    this.MISC2 = "";
    this.MISC3 = "";
    this.UIDsign = "";
    this.UIDupdate = null;
    this.UIDuppgm = "";
    this.UIDuptime = "";
}

Yes, JS does not do any argument prototype checking, and you don't need
to name the parameters in the function definition.

The arguments are placed in an automagically-created object called arguments,
and then the elements are placed in any named parameters there might be.

function foo(a,b) {
	// a contains arguments[0]
	// b contains arguments[1]
	// further arguments are just in arguments[2] onwards.
}

foo(11,22,33,44); // a=arguments[0]=11, b=arguments[1]=22, arguments[2]=33, arguments[3]=44

Since in your example, the generated function doesn't use arguments[],
the 1 passed in is ignored.
