What type of design pattern is the AngularJS $scope object?

I'm new to SO and have been learning and working with JavaScript and AngularJS for about 3 months, so super super new to the field. I'm in the process of going deeper into JS and am studying Design Patterns, so a question popped up in my head -> What type of design pattern is the $scope object?

I have done a fair bit of reading but other than the obvious -> being part of the MVC architecture of AnguarJS, I can't imagine anything more specific.

I'm looking forward to hearing some more experienced developers's answers on this.
