Learned essential jQuery and decided to improve a list exercise by writing a shopping list creator. After entering the quantity and type of item you are planning to get, you click on ADD to create the list. You can also remove an item by clicking on it. This list is fairly dumb in that it can’t discern the type of data entered into the fields right now. The next step will be to add a function to check that quantity is a number and not a string, returning an error message if the user does not input a quantity or a quantity that appears to be too high and thus an error. The ability to specify if a quantity is meant to represent number or weight is also another jQuery function I intend to learn.
