usage of react components not recognized

The following code results in two warnings: React and Article unused. Is this expected ?

import React from 'react'
import Article from './components/article/Article'
import PropTypes from 'prop-types'

function ArticleList ({data, itemState}) {
  const listElements = data.map(p => <li key={p.id}><Article data={p.attributes} state={itemState(p.id)}/></li>)
  return (<ul className="results">
    {listElements}
  </ul>)
}

ArticleList.propTypes = {
  data: PropTypes.array,
  itemState: PropTypes.func
}

export default ArticleList

No, I’m using Article inside the map function and React is required to make things work. It seems that usages of React components like <Article/> are never recognized.
