Perl is a well-liked web-oriented computer programming language, that is designed to generate CGI scripts as well as various apps. It is really handy owing to the fact that you do not have to generate the very same code repeatedly so as to have some task executed more than once, but you will be able to use modules. These are pre-defined subroutines or groups of operations that can be called and executed in a script. That is to say, you will be able to add just a reference to a given module in your code as an alternative to using the entire module code again and again. This way, your script will be shorter, which means that it'll be executed much faster, not mentioning that it'll be easier to maintain and modify. When you wish to use a third-party ready-made Perl script rather than creating your own, it will most likely need particular modules to be pre-installed on the hosting server.
