E-commerce-app made using react

Great Challenge @kabir-afk

At first sight, contribution i can make is that when one click on the button after invoking addToCart , It will be a good behavior to set back numberOfItems to 0 like the following:

<button
    className="addToCart"
    onClick={() => {
           props.addToCart({ numberOfItems })
            setNumberOfItems(0)
            }}
 >

To be able to delete the products from the cart for each button of the product, you can add an attribute that will have a unique number as its value. You will select the button after the index and then you will implement the product deletion function.
