How to use .slice with media query-CodePudding

I'm trying to slice objects whenever the screen is 600px and down, I'm using this code in react to know if the screen is 600px or down

  const [matches, setMatches] = useState(
    window.matchMedia("(max-width: 600px)").matches
  )

  useEffect(() => {
    window
    .matchMedia("(max-width: 600px)")
    .addEventListener('change', e => setMatches( e.matches ));
  }, []);

I'm trying to show pictures

return (
    <div className="shopsHomeFeedImgsCont">
      {shops.map((shop) => (

        <img className="shopsHomeFeedImgs"
        src={shop.shopPic} />
        
      )).slice(0, 2)}
    </div>
);

My question is how slice(0, 2) only when the screen is 600px and down?

CodePudding user response：

You can use your matches state to make your shops data depend on the match query result.

const shopsToBeRendered = matches ? shops.slice(0, 2) : shops;

return (
    <div className="shopsHomeFeedImgsCont">
      {shopsToBeRendered.map((shop) => (
        <img className="shopsHomeFeedImgs" src={shop.shopPic} />
      ))}
    </div>
);
