Write a paragraph or two about what you learned doing this exercise.

2) Implement a web page that performs tip calculations. At a minimum, you will need an input element each for the original cost and for the tip rate, and a button to trigger calculations. Use input type=”number” to make input processing a little easier. Use the DOM to access the elements in the web page. Do not use the prompt, alert, or document.writeln methods.
