Perl is a well-liked web-oriented computer programming language, that's employed to generate CGI scripts as well as many different applications. It's really practical for the reason that you don't have to submit the same program code again and again in order to get some process executed more than once, but you're able to employ modules. They are pre-defined subroutines or groups of operations that can be called and executed within a script. This means that, you can add just a reference to a specific module inside your program code as an alternative to using the entire module code time and time again. In this way, your script will be shorter, thus it will be executed a lot faster, not mentioning that it will be a lot easier to maintain or modify. In case you want to use some third-party ready-made Perl script as an alternative to creating your own, it'll probably need specific modules to be present on the website hosting server.
