What steps are involved in creating a function within AngularJS?

Just starting out with AngularJS and looking to implement a shopping cart using WebSQL. Wondering how to create functions for adding items to the cart and removing them.

Here's the code snippet I have so far:

angular.module('ecommerce').factory('CartService',
    ['$webSql', '$http', '$q', 'urls',
        function ($webSql, $http, $q, urls) {

            var factory = {
                addToCart: addToCart,
                removeCart: removeCart
            };

            return factory;
        }
    ]);

Answer №1

There are various ways to create functions. In your specific scenario:

Option 1: Using Function Expression

angular.module('ecommerce').factory('CartService',
['$webSql', '$http', '$q', 'urls',
    function ($webSql, $http, $q, urls) {
        var addToCart = function () {//function body}
        var factory = {
            addToCart: addToCart,
            removeCart: removeCart
        };

        return factory;
    }
]);

Option 2: Using Function Declaration

angular.module('ecommerce').factory('CartService',
['$webSql', '$http', '$q', 'urls',
    function ($webSql, $http, $q, urls) {
        function addToCart() {//function body}
        var factory = {
            addToCart: addToCart,
            removeCart: removeCart
        };

        return factory;
    }
]);

A function expression is distinct from a function declaration as it assigns the function to a variable name.
