Javascript: email address and password validation

Our goal is to prepare a validation library that is reusable and extensible. We don't want to have to change the validation function every time we start a new project, nor do we want to have to write everything over again. We want a framework for our validation that is easy to use.

in this tutorial (which can be used as a stand alone tutorial as well as part of the series) we examine validating an email address format and a password format
