JavaScript Call function directly after constructor “new” call function directly,call lambda function directly,javascript call function

In many languages, to invoke some function directly on new instance I need to wrap it into braces:

 (new Date()).toString()

In JS new Date().toString() and Date().toString() give the same results as well.

Is it allowed to use function call immediately after instantiating new object in this way?

It looks like new keyword is optional sometimes. How is this interpreted by JS engine?
