Hack

Meta, Menlo Park, California, United States

Hack is a PHP-based programming language designed for the HHVM virtual machine and developed by Meta to build large-scale web applications with improved type safety.

It introduces gradual static typing with features such as nullable, generic, and shape types, async and await for concurrent programming, collections with strict typing, lambda expressions, attributes for metadata, and a type checker that runs alongside code execution.

Hack differs from PHP by enforcing stronger type constraints and providing compile-time error detection, more predictable behavior through strict mode, and improved performance on HHVM, while maintaining interoperability with existing PHP codebases.
