No one should write imperative render code like these in React. There is no need to use class components ever, you have Hooks now. Thus my whole component is reduced to:

const ItemList = ({items}) => (
  <div classname="list-container">
    {
      items.length
      ? <ul>
        { items.map(item => <li key={item.id}>{item.name}</li>) }
        </ul>
      : <p>No items Found</p>
    }
  </div>
);
