Tip Calculator App

What are you most proud of, and what would you do differently next time?

I decided to work from mobile first, I liked how it turned out.

I also challenged myself to format the results un different ways, there's a function that formats the totals with periods for thousands and millions, and if the total reaches the billions it changes to exponential notation.

What challenges did you encounter, and how did you overcome them?

it was a bit of a struggle to code the logic since there where many moving parts, I worked on each one at a time and the refactored my code as I went along to reuse different functions.
