## Description
|
|||
|
|
<section id="description"> Redux存储对象提供了几种允许您与之交互的方法。例如，您可以使用<code>getState()</code>方法检索Redux存储对象中保存的当前<code>state</code> 。 </section>
|
|||
|
|
|
|||
|
|
## Instructions
|
|||
|
|
<section id="instructions">上一个挑战中的代码在代码编辑器中更简洁地重写。使用<code>store.getState()</code>从<code>store</code>检索<code>state</code> ，并将其分配给新变量<code>currentState</code> 。 </section>
|
|||
|
|
|
|||
|

- text: 对于初始状态，redux存储的值应为5。
|
|||
|
|
testString: 'assert(store.getState()===5, "The redux store should have a value of 5 for the initial state.");'
|
|||
|
|
- text: 应该存在一个变量<code>currentState</code> ，并且应该为其分配Redux存储的当前状态。
|
|||
|
|
testString: 'getUserInput => assert(currentState === 5 && getUserInput("index").includes("store.getState()"), "A variable <code>currentState</code> should exist and should be assigned the current state of the Redux store.");'
