How to repeat an element n times using JSX

The shortest way to do this without any external libraries:

const n = 8; // Or something else

[...Array(n)].map((e, i) => <span className="busterCards" key={i}>♦</span>)

solution without lodash or ES6 spread syntax:

Array.apply(null, { length: 10 }).map((e, i) => (
  <span className="busterCards" key={i}>
    ♦
  </span>
));

Here you go:

let card = [];
_.times(8, () => {
  card.push(<span className="busterCards">♦</span>);
});

You may want to add key to each span element so React won't complain about missing the key attribute:

let card = [];
_.times(8, (i) => {
  card.push(<span className="busterCards" key={i}>♦</span>);
});
