Unfortunately, JavaScript has no signature-based dispatch, or
multi-clauses with pattern matching :-).
But as another option, you could use your constructor as a dispatch for
more specific setup methods. Also, rather than listing all the possible
arguments, you can just use the built-in 'arguments' array and inspect them:
construct : function() {
this.id = arguments[0];
if (arguments.length > 1)
this._construct1(arguments.slice(1));
}
This dispatch can be arbitrary complex:
construct : function() {
this.id = arguments[0];
if (typeof(arguments[1]) === 'number')
this._construct1(arguments.slice(1));
else if ((typeof(arguments[1]) === 'string') && (arguments[1] ===
'foobar'))
this._construct2(arguments.slice(1));
else if ...
this._construct3(arguments.slice(1));
...
}
