Perl is a well-liked web-oriented computer programming language, that's employed to make CGI scripts and a variety of apps. It's really handy due to the fact that you do not have to generate the same code over and over in order to get some action executed a couple of times, instead you'll be able to apply modules. They are pre-defined subroutines or groups of tasks that can be called and executed within a script. This means that, you are able to include just a reference to a particular module within your program code as an alternative to using the entire module code again and again. In this way, your script will be shorter, thus it shall be executed faster, not mentioning that it'll be a lot easier to maintain or modify. In case you would like to employ some third-party ready-made Perl script instead of writing your own, it'll probably need particular modules to be present on the web hosting server.
