// These are also the same function as below, with slightly different syntax.

function new (constructor, args) {
    var binding = Object.create(constructor.prototype);
    var retval = constructor.apply(binding, args);
    if (retval === null || typeof retval !== 'object') {
        return binding;
    }
    
    return retval;
}

new.js

function new (constructor, args) {
    var binding = Object.create(constructor.prototype);
    var retval = constructor.apply(binding, args);
    if (retval === null || typeof retval !== 'object') {
        return binding;
    } else {
        return retval;
    }
}

Given a constructor Foo, new Foo(a, b, c) would be the same as new(Foo, [a, b, c]).

I say would be, because new is a reserved word, so the function doesn't actually compile.
