Perl is a well-liked programming language and among its major advantages is the fact that it supports the so-called modules - short pieces of code which include subroutines and execute different tasks. The beneficial side of working with modules is the fact that you won't need to write custom program code or include the entire code for a specific task every single time it should be executed. Instead, you'll be able to add only one line in your Perl script that calls a particular module, which in turn will perform the needed action. Not only will this result in shorter and more optimized scripts, but it will also enable you to make adjustments a lot quicker and much easier. In case you are not a programmer, yet you'd like to employ a Perl app which you've found on the Internet, for example, it is likely that the app will need certain modules to be already set up on the hosting server.
