What it is
This is a large reference collection that shows the same simple 'Hello, World' program written in many programming languages, including mainstream ones and many experimental or joke languages. The README says it lists 1009 languages and links each one to its own example. People use it to compare how different languages look and to find a starting point for a language they have not used before.
- Browse the language list to see how a given language prints text
- Compare the syntax of two or more languages side by side
- Find a minimal starting example for a language you are learning
- Contribute a new language example by following contributing.md
Great for
- Students comparing how different languages handle the same simple task
- Developers curious about an unfamiliar language and wanting a minimal example
- Esoteric-language enthusiasts looking for examples of unusual languages
- Contributors who want to add or fix a language example, following the contributing guide
Not ideal for
- Someone who needs a full tutorial or structured course, since each entry is only a single short program
- Anyone needing production code, libraries, or working software to install, because this is a collection of examples and not a tool

Strengths
- Covers a very wide range of languages, with 1009 listed in the README
- Simple, consistent format that makes comparison easy
- Open to contributions, with instructions in contributing.md
Trade-offs
- Each entry is a single short program, so it teaches little beyond basic output syntax
- The README does not state how often entries are checked for correctness or whether they all still run
