javascript - Render an array of Objects in ReactJs

Question

I am trying to go through object properties (Name for this example) and list them within easy loop in function. I have found some pretty awkward way of doing this but it doesn't seem right.

Here is what i got:

const ItemsToSell = [{"Name":"Cup","Price":"99.99"},{"Name":"IPhone","Price":"99.99"},{
"Name":"Pen","Price":"99.99"}]

function ListItem(props) {
  return <li>{props.value}</li>;
}

function NumberList(props) {
  const a = props.numbers;
  return (
    <ul>
      {a.map((number) =>
        <ListItem  value={ItemsToSell[number].Name} />
      )}
    </ul>
  );
}

const numbers = [0,1, 2];
ReactDOM.render(
  <NumberList numbers={numbers} />,
  document.getElementById('root')
);

You can simply map over ItemsToSell array

const ItemsToSell = [{"Name":"Cup","Price":"99.99"},{"Name":"IPhone","Price":"99.99"},{
"Name":"Pen","Price":"99.99"}]

function ListItem(props) {
  return <li>{props.value}</li>;
}

function NumberList(props) {
  return (
    <ul>
      {ItemsToSell.map((obj, index) =>
        <ListItem  key={index} value={obj.Name} />
      )}
    </ul>
  );
}

ReactDOM.render(
  <NumberList  />,
  document.getElementById('root')
);
