Add removeFromCart() to the foodItem prototype. The method has a single parameter named cart representing the shopping cart from which the item should be removed. Loop through the items array in the cart object and for each item test whether it is equal to the foodItem object. If it is, use the splice() method to remove the object from the items array and break off the for loop. (Hint: Use the this keyword to reference the foodItem object and use the splice(index, 1) to remove the foodItem where index is the counter variable in the for loop."
