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getState()方法检索Redux存储对象中保存的当前state 。

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store.getState()从store检索state ，并将其分配给新变量currentState 。

Tests

tests:
  - 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.");'

Challenge Seed

const store = Redux.createStore(
  (state = 5) => state
);
