Create a set of HTML and JavaScript files , that will include a text box for user input that will say "What's your age?"

There should be a button that says Enter on it. When the button is clicked, an evaluation should be done.

If value is (NaN), then you should display an alert box saying, Not a number. The same goes for when the user enters a 0 or a negative number. If the entry is valid, then you must appropriately test the input.

If the user entered:

A number that is greater than or equal to 5, then you should display a Sandwich picture

A number that is less than 5, then you should display the Milk picture
