Formatting Phone Number Inputs

This video is a response to a great YouTube comment I got an a very old video of mine going over an interview question a student had received, which was to write a function that could take variable length number values, and format them to the appropriate style with parentheses for area codes, plus sign for international codes, and hyphenating the final 7 numbers.
I had a great time learning about the nuances of how browsers handle programmatically assigning values. Hopefully y'all learn something cool, too!
