**Styleguide Reference**

* [y024 by johnpapa - Named vs Anonymous Functions](https://github.com/johnpapa/angular-styleguide/blob/master/a1/README.md#style-y024)

## Examples

The following patterns are considered problems when configured `"anonymous"`:

    /*eslint angular/function-type: [2,"anonymous"]*/

    // invalid
    angular.module('myModule').factory('myService', myServiceFn);
    function myServiceFn() {
        // ...
    } // error: Use anonymous functions instead of named function

The following patterns are **not** considered problems when configured `"anonymous"`:

    /*eslint angular/function-type: [2,"anonymous"]*/

    // valid
    angular.module('myModule').factory('myService', function () {
        // ...
    });

The following patterns are considered problems when configured `"named"`:

    /*eslint angular/function-type: [2,"named"]*/

    // invalid
    angular.module('myModule').factory('myService', function () {
        // ...
    }); // error: Use named functions instead of anonymous function

The following patterns are **not** considered problems when configured `"named"`:

    /*eslint angular/function-type: [2,"named"]*/

    // valid
    angular.module('myModule').factory('myService', function myService() {
        // ...
    });

    // valid
    angular.module('myModule').factory('myService', myServiceFn);
    function myServiceFn() {
        // ...
    }
