The zxcvbn.js JavaScript open source library provides us with a simple easy to use function for evaluating the strength of a password the user enters. Using this library we can provide our user with an immediate feedback.
The following code sample shows how simple it is to use this JavaScript open source library. You can find the files ready for download as part of the Zxcvbn.js Basics free course at http://abelski.lifemichael.com.
