Jello: Print “jello ” in every programming language

That doesn't seem like a very interesting choice. `print hello` or similar will not showcase much of any given language's syntax, and is actually likely to hit specialized syntax for printing (e.g. Python 2's print wasn't a function). It will show some of the boilerplate, for languages that need it (public static void main...).

"Every programming language" is also quite the claim, I only see 46 languages in there (Wikidata counts 1,449 "programming languages" Q9143).

Has a bunch of different concepts implemented in a TON of different programming languages. Here's an example for the typical FizzBuzz exercise: https://rosettacode.org/wiki/FizzBuzz (321 languages currently)

Awesome! I apologize to pull the classic HN move but I built something similar with FizzBuzz, with the requirement that implementations run within a docker container (it was a project to learn Docker). https://github.com/jdan/fizzbuzz-polyglot

Thanks for putting this together though, you've got quite a suite here.

Is this a postmodern fork of some "hello" repo? Why "jello", and why does the Readme say "hello" instead?

Is the longest program in terms of lines of code the one written in Whitespace? (14 lines). It’s also the shortest program if you don’t count whitespace.
