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

app.controller('mainCtrl', function() {
  this.name = 'World';
});

I'm seen in most of the tutorial they do angular.module('app',[]), what does app mean? is it just the name of the module? I've seen in few large project where the name of the module never change, it's always app. I'm confused what is the .module method for.

Second question is why the above example doesn't work with this keyword? it worked if I do

app.controller('mainCtrl', function($scope) {
  $scope.name = 'World';
});

It's the name you chose to name the module. – Stubbies Dec 30 '16 at 02:26
@Erevald what is it for? I want to know how to use the module in angularjs. The purpose is it to create multiple modules? can modules talk to each other? – Nately Jamerson Dec 30 '16 at 02:29
`this.` vs `$scope` is already explained [here](http://stackoverflow.com/a/14168699/1373110) – Stubbies Dec 30 '16 at 02:33
@NatelyJamerson you can define this ``var myApp = angular.module('myApp ', []);`` – Donald Wu Dec 30 '16 at 03:11
then ``myApp.controller('mainCtrl', function($scope) { $scope.name = 'World'; });`` – Donald Wu Dec 30 '16 at 03:12
@DonaldWu I know and I've use angular for quite some time but why? What's the point of having multiple modules? – Nately Jamerson Dec 30 '16 at 05:31
@NatelyJamerson no idea, but u can see this post http://stackoverflow.com/questions/18512434/multiple-module-in-angularjs – Donald Wu Dec 30 '16 at 07:15
