Jako, commonly referred to as "Jakk", is a programming language created by Gregor N. Purdy. It is similar to C++, but makes several large deviations, in some ways making it closer to Perl. Jakk can be compiled into Parrot's assembly language, PASM, and then run on the Parrot virtual machine. Hello world in Jakk is:
use sys; sys::print("Hello, world!\n");
