new and ()

[Chris.Nelson]

I understand the difference between:

function foo() { /* more here */};

var x = foo;

and

function foo() { /* more here */};

var x = foo();

The former assigns x the function foo and the latter assigns x the result of invoking foo(). But I don't understand how this interacts with new; I've seen "var o = new Object;" and "var o = new Object();"? Is that the same distinction?

Javascript has a very forgiving syntax. You don't have to write semi-colons to separate statements -- a newline will do. Likewise, you don't have to put the empty parameter list, when using a function as constructor. It doesn't hurt to put it there though, and for sake of readability, it's good to be consistent.

So new Foo and new Foo() are completely interchangeable.
