вот функция как поставить проверку если свойство isFavorits true то он отрисует карточку?

{isFavorite && Карточка}

Где карточк

Либо так либо нулл из компонента вернуть

поставь гард. Если условие не выполняется, просто верни ничего. В ином случае верни карточку function Favorites({ offers }) { return ( offers.map((offer) => { if (!offer.isFavorite) { return } return <section ...> ... } )}
