Perl is an effective programming language that's widely used for making CGI scripts along with different web-based applications. One of its key pros is the fact that it works with modules - ready-made batches of program code which are designed to perform various tasks and to extend the functionality of a certain script without slowing it with unneeded lines of code. To put it simply, if five jobs should be performed, you'll be able to use five lines of program code in order to call each one of the modules rather than adding hundreds of lines used to create the actual modules within your script. Perl is really useful and it may be used for various purposes, that's why many corporations have included it in their web products or on their high-traffic websites - cPanel, IMDB, Craigslist, BugZilla, BBC and many more. It's ordinarily used along with other languages for example PHP or Python.
