任何人都可以在打字稿中解释 <->

Question

new to typescript can anyone explain what is the meaning of this sign <->? Just to confrim, ProductList is actually a function? in the following code.

 export const ProductList: React.FC<-> = ({ displayLoader, hasNextPage, notFound, onLoadMore, products, totalCount, }) => { const hasProducts = !!totalCount; return ( <div className="products-list"> <div className="products-list__products container"> {hasProducts ? ( <> <div className="products-list__products__grid"> {products.map(product => ( <Link to={generateProductUrl(product.id, product.name)} key={product.id} > <ProductListItem product={product} /> </Link> ))} </div> <div className="products-list__products__load-more"> {displayLoader ? ( <Loader /> ) : ( hasNextPage && ( <Button secondary onClick={onLoadMore}> Load more products </Button> ) )} </div> </> ) : ( <div className="products-list__products-not-found">{notFound}</div> )} </div> </div> ); };

Please advice. Thank you so much.

There should be an interface that will describe a shape of your props object instead of - . Should look something like this React.FC<IProductListProps> . You might get that mistake while copy-pasting. There is no such operator like this <-> in TypeScript
