Defining instances in an array

How does creating instances in an array without assigning them a variable work? He's assigning them when he defines the array? That' isn't making any sense. Is there any sources out there on this? I've been searching and can't find anything even close. I don't understand why no one would cover adding instances to arrays. Thank you.

These instances ARE being assigned to a variable. They are being assigned to the array variable questions.

The code in the video is essentially the same as this:

var questions = [];
questions[0] = new Question(blabla...);
questions[1] = new Question(blabla...);

The video method just defines and assigns the array at the same time. It's just a short cut.

Ah, if only the teacher had said that. Oh well, thanks for the response Steven. The code example was really helpful.
