Perl is a well-liked web-oriented programming language, that's employed to set up CGI scripts along with various apps. It's very practical owing to the fact that you don't need to write the same code again and again to have some action executed more than once, instead you can use modules. They're pre-defined subroutines or sets of tasks that can be called and executed in a script. This means that, you'll be able to add only a reference to a certain module inside your code as an alternative to using the entire module code over and over again. In this way, your script will be shorter, which means that it will be executed quicker, not mentioning that it will be much easier to maintain and / or modify. If you wish to employ a third-party ready-made Perl script rather than creating your own, it will most likely need specific modules to be present on the web hosting server.
