Password Strength Regex

Regular Expression (Regex) is a really important part of coding and server management. It allows you to do many checks in a one command.
An example would be to check a file, files, directory, or your entire file system with grep. An email validator on a web form. User input meets requirements in a command line application, and so much more. I want to break down Regex in this simple tutorial using a password strength checker. Simply put if it meets all the requirements then it will pass and if not then it will fail. Simple?

Summary

I will provide explanations, definitions, and examples. All examples will be formatted for JavaScript.
