| # --description--
 | ||
| 
 | ||
| `dispatch` 方法用于将 action 分派给 Redux store, 调用 `store.dispatch()` 将从 action creator 返回的值发送回 store。
 | ||
| 
 | ||
| 回想一下,动作创建者返回一个具有 type 属性的对象,该属性指定已发生的动作。 然后该方法会将一个 action 对象发送到 Redux store。 基于上一个挑战的示例,下面的行是等效的,两者都会调度类 `LOGIN` 类型的 action:
 | ||
| 
 | ||
| ```js
 | ||
| store.dispatch(actionCreator());
 | ||
| store.dispatch({ type: 'LOGIN' });
 | ||
| ```
 | ||
| 
 | ||
| # --instructions--
 | ||
| 
 | ||
| 代码编辑器中的 Redux store 具有初始化状过的 state,包含 `login` 属性当前设置为 `false`的对象, 还有一个名为 `loginAction()` 的 action creator,它返回类型为 `LOGIN` 的 action, 然后通过调用 `dispatch` 方法将 `LOGIN` 的 action dispatch 给 Redux store,并传入 `loginAction()` 创建的 action。
 | ||
| 
 | ||
| # --hints--
 | ||
| 
 | ||
| 调用函数 `loginAction` 应该返回一个 `type` 属性设置为字符串 `LOGIN` 的对象。
 | ||
| 
 | ||
| ```js
 | ||
| assert(loginAction().type === 'LOGIN');
 | ||
| ```
 | ||
| 
 | ||
| store 应该用属性 `login` 设置为 `false` 的对象初始化。
 | ||
| 
 | ||
| ```js
 | ||
| assert(store.getState().login === false);
 | ||
| ```
 | ||
| 
 | ||
| `store.dispatch()` 方法应该被用于 dispatch 一个类型为 `LOGIN` 的 action。
 | ||
| 
 | ||
| ```js
 | ||
| (getUserInput) =>
 | ||
|   assert(
 | ||
|     (function () {
 | ||
|       let noWhiteSpace = getUserInput('index').replace(/\s/g, '');
 | ||
|       return (
 | ||
|         noWhiteSpace.includes('store.dispatch(loginAction())') ||
 | ||
|         noWhiteSpace.includes("store.dispatch({type: 'LOGIN'})") === true
 | ||
|       );
 | ||
|     })()
 | ||
|   );
 | ||
| ```

| const store = Redux.createStore(

|     type: 'LOGIN'

| };

| 
 | ||
| store.dispatch(loginAction());
