Introduction to Perl

Perl is an open-source, high-level, general-purpose programming language that was created in 1987 by Larry Wall. It was originally designed for the processing of text but has since evolved into a fully featured programming language that is utilised in web development, system administration, network programming, and more.

Perl runs on over 100 platforms, including Microsoft Windows, Linux and macOS. It is a multi-paradigm language that supports procedural, functional and object-oriented programming.

As well as its core functionality, there are over 25,000 open-source modules available from the Comprehensive Perl Archive Network, or CPAN for short.
