Is () requested for invoking a Flex ActionScript constructor?

Question

In Flex ActionScript, a new object can be instantiated via the parameterless constructor with or without (). Example:

var array:ArrayCollection = new ArrayCollection()

or

var array:ArrayCollection = new ArrayCollection

Is there a difference between the two? Is one preferred over the other?

Answer 1

I think there is no difference functionally, but I like having the () just because of convention.
