In the ProductList component, useMemo with an empty dependency array is used. How does this affect the display of new products? Also, in the AddProductForm component, the button attaches onClick to handleSubmit instead of using onFinish on the form — how to fix this correctly?

Using useMemo with an empty dependencies array ([]) means that memoization will occur only once during the initial render of the component. In the case of the ProductList component, this means that if the list of products changes, the memoized value will not update, and new products will not be displayed. To display current data, dependencies in useMemo should include the variable with the products, for example:
const memoizedProducts = useMemo(() => products, [products]);
Regarding AddProductForm, if the button calls handleSubmit via onClick, it may cause issues with validation and form behavior. The correct way is to use the onFinish handler on the <Form> element, which is called after successful validation. The button should have htmlType="submit" to trigger form submission:
<Form onFinish={handleSubmit}>
{/* form fields */}
<Button htmlType="submit">Add</Button>
</Form>
This way, the form handles validation and submission properly.
