Perl is a well-liked programming language and one of its key pros is the fact that it supports the so-called modules - short pieces of code that include subroutines and perform multiple tasks. The useful side of employing modules is the fact that you will not have to write custom-made code or include the whole code for some task every time it should be executed. Alternatively, you are able to add just a single line in your Perl script which calls a certain module, which consequently will execute the necessary task. Not only will this give you shorter and enhanced scripts, but it will also enable you to make adjustments swifter and much easier. If you are not a programmer, yet you'd like to begin using a Perl app which you've found online, for example, it is very likely that the application will need specific modules to be already installed on your website hosting server.
