requires meaning an array of modules which your module depends.

example:

moduleA.js

var customModule = angular.module ('ModuleA');
// controller, services, factories , etc codes here

app.js (main app)

var app = angular.module ("app", ["ModuleA"]);

if I just use:

angular.module ("app");

It means that i'm just retrieving the module named "app". Which is useable when controllers or directives or factories is defined in a different JS files and you want to configure it to the module "app"
