trying using it this way, i dont understand why .length does'nt work either.

const isEmpty = () => {
        if (cart.line_items === 0) {
            return true
        } else {
            return false
        }
    }

If stuck, just look for any response changes from the commerce API call. Here's how I solved it: {!cart.line_items ? ShowEmptyCart() : ShowFilledCart()} or {!cart.line_items ? <ShowEmptyCart /> : <ShowFilledCart />}

Happy Coding! ☺
