Perl is a well-liked programming language and one of its main pros is the fact that it works with the so-called modules - short pieces of program code that contain subroutines and execute numerous tasks. The beneficial side of working with modules is that you do not have to write custom-made code or include the entire code for a particular action every single time it has to be performed. Alternatively, you'll be able to add just a single line in your Perl script that calls a particular module, which consequently will perform the needed action. Not only will this lead to shorter and enhanced scripts, but it will enable you to make modifications a lot quicker and much easier. In case you aren't a programmer, yet you would like to use a Perl application which you've discovered on the web, for instance, it is very likely that the application will need some modules to be already set up on the web hosting server.
