How can I construct an object using an array of values for parameters, rather than listing them out, in JavaScript?

Answer 1

what about a workaround?

function MyClass(arg1, arg2) {

    this.init = function(arg1, arg2){
        //if(arg1 and arg2 not null) do stuff with args
    }

    init(arg1, arg2);
}

So how you can:

var obj = new MyClass();
obj.apply(obj, args);
