checking if Object children are null in javascript

I have an object and I want to check if its fields are null or not and then I want to send a request. here is my code:

const [newProduct, setNewProduct] = useState({
    name: null,
    cost: null,
    size: null,
    color: null,
    material: null,
    discount: null,
    description: null,
    category: null
});

const addNewProduct = () => {
    if(newProduct.name && newProduct.cost && newProduct.size && newProduct.color && newProduct.material && newProduct.discount && newProduct.description && newProduct.category) {
        let productFormData = new FormData();
        productFormData.append('productInfo', JSON.stringify(newProduct));
        productFormData.append('productImages', images.imageFiles);

        const addUrl = "http://localhost:8080/cpnl/addproduct";
        axios({
            method: "POST",
            url: addUrl,
            data: productFormData,
            headers: { "Content-Type": "multipart/form-data" }
        })
            .then((response) => {
                console.log(response.data.msg);
            })
            .catch((response) => {
                console.error(response);
            });
    }
};

Is there a way to make if statement shorter? do I need to define all fields to modify them?
