How to display state on page in jsx?

I just started looking at react/redux this is my component:

const store = createStore(reducer);

const rootEl = document.getElementById('root')

//render root component
const render = () => ReactDOM.render(

  {store.getState()}


  <List

    addToList={() => store.dispatch(
      {
        type: 'ADDTEXT',
        payload: {
          text: 'this is a text'
        }
      }
    )}
      />

  ,
      rootEl
      )

//call
      render()

//subscribe the store
      store.subscribe(render)

I thought I could mix up js with html but the store.getState() gives me this error:

Syntax error: Unexpected token (22:8)

  20 | const render = () => ReactDOM.render(
  21 | 
> 22 |   {store.getState()}

How can I display the state on the UI?

The problem here is simple. JSX doesn't support returning multiple JSX nodes. Read more here.

So put all of this in a single div, and it shall work :)

<div>
  {store.getState()}
  <List addToList={() => store.dispatch({
      type: 'ADDTEXT',
      payload: {
        text: 'this is a text'
      }
    })
  }/>
</div>
