The MEAN Stack

The MEAN stack is what happens when JavaScript developers look at the server and say 'we can take that too.' MongoDB stores your data as JSON (because everything is JSON now), Express handles routing with the quiet competence of a librarian, Angular builds your frontend with more decorators than a Christmas tree, and Node.js ties it all together by running JavaScript on the server — something that was once considered a war crime. It's JavaScript all the way down, which is either brilliant or terrifying depending on your relationship with callback functions.
