This is an AngularJS code snippet that we used for our blog post https://rubygarage.org/blog/react-vs-angularjs at RubyGarage. It demonstrates how we inject dependencies in an AngularJS module using an $inject property. This code snippet was taken from a well-known TodoMVC application.

// an example from GitHub
angular.module('todomvc')
  .controller('TodoCtrl', TodoCtrl);

function TodoCtrl(s, r, f, a) {
  'use strict';
  var todos = s.todos = a.todos;
  s.newTodo = '';
  s.editedTodo = null;
  // missing function code is omitted for brevity
};
//inject dependencies using a special function
TodoCtrl[“inject”] = [“$scope”, “$routeParams”, “$filter”, “store”];
