What is the difference between date and date()

Question

On Node.js, when I execute the following two statements:

console.log(new Date);
console.log(new Date());

Both produce the same result.

What is the difference?

I have been told to use new Date(), although no reason was given.

Answer 1

from the syntax of new operator:

new constructor[([arguments])]

the parentheses is optional, so both expressions are valid.

console.log(new Date);
console.log(new Date());
