Tests:

matchMedia + addListener
const matchMedia = window.matchMedia("(min-width: 400px)"); matchMedia.addListener((query) => { if (query.matches) { console.log(true); } })
resize + innerWidth
let currentWidth = window.innerWidth; window.addEventListener('resize', () => { currentWidth = window.innerWidth; }); if (currentWidth > 400) { console.log(true); }
