I would challenge anyone reading this to dive in deeper on each section. This is a GREAT surface article, but could be built upon for different needs. Understanding regex takes time and practice. Even the above example would allow a phone number like 000-000-0000 - which is valid according to your regex, but obviously is not a real phone number. So, dive a little deeper, find the constraints and patterns that need to be checked - and in what order - to compile a valid, working, phone number. Also, as a side note - you have references to [\s-] and [a-z-], in which case I would ALWAYS put the hyphen in first. This is because the hyphen can also define a range (a-z), so having it first ensures that it is not trying to match a range of letters/numbers because nothing will come before it. Nice read!
