React remove object from list of objects without unique value, using hooks

Question

I want to remove object from my list by clicking on delete icon, but with my logic either everything is deleted from list or nothing, I am not sure how to do it without provided ID to object, I don't have anything unique and I am kinda lost. Component that renders as many Food as there is in useState:

 {cartFood.map((food) => {
    return (
      <CartFood
         key={Math.random()}
         foodName={food.foodName}
         foodPrice={food.foodPrice}
         numberOfPortions={food.numberOfPortions}
         cartFood={cartFood}
         setCartFood={setCartFood}
      />
    );
 })}

Logic for removing that particular item that is selected (which is not working and also bad solution since there can be case where you get same name and price twice)

const CartFood = ({
  foodName,
  foodPrice,
  numberOfPortions,
  cartFood,
  setCartFood,
}) => {
  const handleRemoveFood = () => {
    setCartFood(
      cartFood.filter(
        (el) =>
          el.foodName &&
          el.foodPrice !== cartFood.foodName &&
          cartFood.foodPrice
      )
    );
  };

  return (
    <div className='cartFood-container'>
      <p>{foodName}</p>
      <p>x{numberOfPortions}</p>
      <p>{foodPrice}kn</p>
      <p>
        <MdDeleteForever
          className='cartFood__icon'
          onClick={handleRemoveFood}
        />
      </p>
    </div>
  );
};

export default CartFood;

List of objects looks like this:

[{
  foodName: "Njoki with sos"
  foodPrice: 35
  numberOfPortions: 1
}, 
{
  foodName: "Chicken Wingos"
  foodPrice: 45
  numberOfPortions: 2
}]

Answer 1

• Put the index of the item in the array as the id. Pass it as your id.

 {cartFood.map((food, index) => {
              return (
                <CartFood
                  key={index}
                  id={index}
                  foodName={food.foodName}
                  foodPrice={food.foodPrice}
                  numberOfPortions={food.numberOfPortions}
                  cartFood={cartFood}
                  setCartFood={setCartFood}
                />
              );
            })}

• Use the id to remove the food.

const CartFood = ({
  foodName,
  foodPrice,
  numberOfPortions,
  cartFood,
  setCartFood,
  id,
}) => {
  const handleRemoveFood = () => {
    setCartFood(cartFood.filter((el) => el.id !== id));
  };

  return (
    <div className='cartFood-container'>
      <p>{foodName}</p>
      <p>x{numberOfPortions}</p>
      <p>{foodPrice}kn</p>
      <p>
        <MdDeleteForever
          className='cartFood__icon'
          onClick={handleRemoveFood}
        />
      </p>
    </div>
  );
};
