Perl is a well-liked programming language and one of its major pros is the fact that it works with the so-called modules - short pieces of program code that contain subroutines and execute a variety of tasks. The handy side of using modules is the fact that you will not need to write custom code or add the entire code for a specific action each time it should be performed. Instead, you will be able to include only one line in your Perl script which calls a certain module, that consequently will execute the necessary task. Not only will this lead to shorter and enhanced scripts, but it'll also allow you to make adjustments quicker and much easier. In case you aren't a programmer, yet you'd like to work with a Perl application which you've discovered online, for example, it is likely that the app will require specific modules to be already set up on your web hosting server.
