Question

In javascript, the typical way to new up an object is by doing it like this: new Date(). But you can also do this: new (Date). What is the difference and advantages of doing it the latter way?

Answer 1

There is no difference.

The new operator takes a function reference.
Like any other operator, the operand can have parentheses.

The () after a new expression with no arguments are optional.

However, if you have more a complicated expression inside the parentheses, they can change precedence ordering, such as in this answer.
