Does the Date constructor return something?

The parameter passed in the video for the Treet constructor include new Date(). Is the Date constructor returning something? Don't we need to create the instance first ?

"Don't we need to create the instance first ?" That's exactly what new Date() does, it creates a new instance.

the value will be stored on mCreationDate property

Here's a more detailed answer, as I had the exact same question. The basic idea is, you can do something like new Date(); if you only need that object reference once, but you wouldn't be able to use that object again after that since it wasn't assigned to anything. So if someone wanted to, they could make their code really messy by constantly calling new Date(); to fetch the current date, rather than setting it to a variable as Date date = new Date();.
