angularjsHow do I use an AngularJS factory?

An AngularJS factory is a service that can be used to create custom objects and functions. To use an AngularJS factory, you need to first define it in your application module. For example:

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

app.factory('myFactory', function() {
    return {
        getName: function() {
            return 'John Doe';
        }
    }
});

You can then inject the factory into your controller or service and use the functions it provides. For example:

app.controller('myController', function($scope, myFactory) {
    $scope.name = myFactory.getName();
});

The output of this code would be John Doe.

Code explanation

• var app = angular.module('myApp', []); - This line defines a new AngularJS application module.
• app.factory('myFactory', function() { - This line defines a new factory with the name myFactory.
• return { - This line returns an object containing all the functions and variables that will be available from the factory.
• getName: function() { - This line defines a function called getName which will be available from the factory.
• return 'John Doe'; - This line returns the string John Doe when the getName function is called.
• $scope.name = myFactory.getName(); - This line calls the getName function from the myFactory factory and assigns the returned value to the $scope.name variable.
