title: How to get a nested array value from a redux state
body: <p>This function returns the redux state</p>
  
  <pre><code>this.context.store.getState()
  </code></pre>
  
  <p>Here's the state</p>
  
  <pre><code>Map {size: 2, _root: ArrayMapNode, __ownerID: undefined, __hash: undefined, __altered: false}
  </code></pre>
  
  <p>If I do this.context.store.getState()["size"] it will return 2, which is perfect. Now I want to retrieve place_id from the following. How do I do it?</p>
  
  <pre><code>{_root:
    entries:
      [place_id: 'TRYING TO GET THIS VALUE"
  </code></pre>
  
  <p>But if I do getState()["_root"]["entries"]["place_id"] it doesn't work (because it's within an array?)</p>
