Regex for URL validation

/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/i

The purpose of this tutorial gist is to explain the regex for URL validation. This regex value demonstrates protocol optional URL validation.

The expression begins with a capture grouping expression. It searches for http in order, with an s as optional. It checks for a : and two //'s to make up https://. That entire part is wrapped in a capture group and is made optional by the ?.

// Write code to loop through the array of numbers
// At each iteration, if a number is evenly divisible by 3 print "Fizz"
// If a number is evenly divisible by 5 print "Buzz"
// If a number is evenly divisible by both 3 AND 5, print "Fizz Buzz"
// If a number is not divisible by 3 or 5, print the number
