Strong, stable, mature and portable

Perl5 is a 26 year old, powerful and performance richprograming language。 Perl can run on more than 100 platforms, from portable devices to mainframe computers. At the same time, she is also suitable for prototype design and large-scale development projects.

If Perl is compared to the family of development languages, Perl 6 is a member of this family, but at the same time, Perl 6 is an independent language with its own independent development team. Her presence has little impact on the continued development of Perl 5.
