Hello world in every programming language

My favorite so far is Malbolge[0]: https://github.com/leachim6/hello-world/blob/master/m/malbol... "Malbolge was specifically designed to be almost impossible to use, via a counter-intuitive 'crazy operation', base-three arithmetic and self-altering code.[1] It builds on the difficulty of earlier, challenging esolangs (such as Brainfuck and Befunge), but takes this aspect to the extreme, playing on the entangled histories of computer science and encryption. Weaknesses in the design have been found that make it…

A couple years ago I wrote Hello World in assembly language for Raspberry Pi using 6 entirely different methods, with the code kept as similar as possible so the differences between the methods are easier to compare. https://github.com/ksaj/helloworld
