angularjs - What is the proper module/directive/filter/etc syntax in angular? -

i've seen modules, , directives, filters, etc defined in modules, written different ways , curious if there benefit 1 on other.

for example, have module defining directive in looks this:

var app = angular.module('app', []);  app.directive('mydirective', function() {     return {         restrict: 'e',         template: '<a href="http://google.com">google</a>'     } });  

but see written following lot, directive definition inside the module:

angular.module('app', []) .directive('mydirective', function() {     return {         restrict: 'e',         template: '<a href="http://google.com">google</a>'     } }); 

which way better? thanks!

it's same.

module(name,dependencies) returns module defined.the difference between 2 in first exemple put module variable.which in exemple 1 unnecessary.

but see written following lot, directive definition inside the module:

it's not inside module,you calling method of module,directive,factory... methods of module.

it's called method chaining.
