Perl is a well-known programming language, that is employed to create various web applications and CGI scripts. Lots of programmers believe that it is one of the most efficient languages in existence as it supports the use of modules - compact parts of code with pre-defined subroutines which are used to execute a particular task. The modules can help you save time and effort and they will contribute to the rapid loading speed of your websites since you are able to include only 1 line of code to call a certain module instead of using all of the program code for the process within your script. Perl is a universal language most often used for scripts, but it has been employed to create a lot of popular pieces of web software as well, like cPanel, BugZilla and Movable Type. It's also used on high-traffic sites like IMDB, Craigslist, Ticketmaster and many others.
