Perl is a preferred scripting language that is which is used to make different web-oriented apps, such as CGI scripts. Among the attributes which differentiate it from various other programming languages is the employment of modules - parts of Perl code which execute predefined jobs and they're widely accepted. Basically, instead of writing custom-made program code to make something or pasting tens and hundreds of lines of program code inside your script, you are able to "call" a module that is already available for this particular process and use just several lines of program code. As a result, your script will be executed much more quickly since it will be much smaller. Using modules will additionally make the script easier to modify because you'll have to browse through much less program code. If you intend to use Perl on your website, you need to ensure that the necessary modules are present on the server.
