Facebook Introduces "Hack" Language, Based On PHP

Facebook has announced Hack, a new scripting language based primarily on PHP and powered by their HHVM interpreter.

Facebook's Hack language is still designed to work with PHP but is statically typed, supports, generics, collections and lambdas support, and other new language features. Another interesting addition is Hack's async implementation for asynchronous PHP programming.

Those interested in more information on Hack can visit Facebook's HackLang.org project site.
