title: In MongoDB, is 'users' a default collection?
body: <p>So I've been learning MEAN through the book 'Mean Machine' and in one of their examples we connect to a db to store user info while creating our RESTful api. Now, every time that we save the user info it gets stored in a collection named 'users' even though no where in the code does it explicitly save to a users collection. Also, when I just create an empty db it does not have the 'users' collection. So, is there something that I'm missing here? Or is 'users' a default collection in MongoDB?</p>
