Perl is a well-liked web-oriented programming language, which is used to generate CGI scripts as well as various applications. It is really handy considering that you do not need to produce the very same code over and over again in order to get some process executed a couple of times, but you're able to apply modules. These are pre-defined subroutines or sets of functions which can be called and executed inside a script. This means that, you will be able to include just a reference to a given module inside your program code as an alternative to using the whole module code time and time again. This way, your script will be shorter, thus it shall be executed a lot quicker, not mentioning that it'll be much easier to maintain and modify. In case you wish to employ a third-party ready-made Perl script as an alternative to creating your own, it'll probably need certain modules to be present on the web hosting server.
