Uncaught Error: [$injector:nomod] Module 'TodoListApp' is not available! You either misspelled the module name or forgot

Here's the error that I'm getting: - Please note that in the error todoListApp begins with capital T as "TodoListApp" and in my code I see it as "todoListApp" everywhere.

Here's my code:

app.js

angular.module("todoListApp", [])

todos.js

angular.module('todoListApp')
.directive('todos', function() {
  return {
    templateUrl: 'templates/todos.html'

  }
})

todos.html

<div ng-controller="mainCtrl" class="list">
  <div class="add">
   <a href="" ng-click="addTodo()">+ Add New Task</a>
  </div>
  <div class="item" ng-class="{'editing-item' : editing,
'edited' : todo.edited}" ng-repeat="todo in todos">
    <input type="checkbox" ng-model="todo.complete"/>
    <label ng-click="editing=true;" ng-hide="editing"  ng-click='helloWorld()'>{{todo.name}}</label>
    <input ng-change="todo.edited = true" ng-blur="editing = false;" ng-show="editing"  ng-model="todo.name" class="editing-label"   type="text"/>
    <div class="actions">
      <a href="" ng-click=" editing = !editing">edit</a>
      <a href="" ng-click='saveTodo(todo)()'>save</a>
      <a href="" ng-click="deleteTodo(todo, $index)" class='delete'>delete</a>

Binding to a variable should not be necessary. My current angular project works fine without that. Try to fix: 

  <script src="scripts/services/data" type="text/javascript"></script> <!-- should be data.js -->

and see if it's going to help. Maybe the flow of scripts gets interrupted by this and something weird happens.At a first glance the app looks fine and should work.

Try to save your module on variable like

var tdApp = angular.module("todoListApp", []);

Then, bind your directives and controller to this variable

tdApp.directive('todos', function() {
  return {
    templateUrl: 'templates/todos.html'

  }
});

tdApp.controller('mainCtrl', function($scope, dataService) { ... });
