Hack is a programming language for the HipHop Virtual Machine (HHVM), created by Meta (formerly Facebook) as a dialect of PHP. The language implementation is free and open-source software, licensed under an MIT License.[2][3][4]
Hack allows use of both dynamic typing and static typing. This kind of a type systems is called gradual typing, which is also implemented in other programming languages such as ActionScript.[5] Hack's type system allows types to be specified for function arguments, function return values, and class properties; however, types of local variables are always inferred and cannot be specified.[3][6]
