In this chapter, we learned how to create a simple Node.js application that read an Apache log file and extracted the log information using a regular expression. We were able to put in to practice the knowledge we acquired in the previous chapters of the book.

We also learned that to create a very complex Regex, it is best to do it in parts. We learned that we can be very specific while creating a regular expression or we can be more generic and achieve the same results.

As a new version of EcmaScript is being created (EcmaScript 6, which will add lots of new features to JavaScript), it is good to familiarize yourself with the improvements related to regular expressions as well. For more information please visit http://www.ecmascript.org/dev.php.

We hope you enjoy the book! Have fun creating regular expressions!
