Frequently Asked Questions
About the Project
- What is Hello World Wiki?
A growing collection of “Hello, World!” programs written in 300+ programming languages — designed for learners, developers, and curious minds.
- How do you categorize the languages?
Languages are grouped into 8 types:
- Compiled – Converted to machine code before running (e.g., C, Rust)
- Educational & Visual – Built to teach programming or use graphical interfaces (e.g., Scratch, Blockly)
- Frameworks & Tools – Frameworks or utilities that produce or run code (e.g., React, Flutter)
- Functional Languages – Emphasize functions and immutability (e.g., Haskell, Elixir)
- Interpreted Languages – Run line-by-line using an interpreter (e.g., Python, Ruby)
- Obscure & Esoteric – Created for experimentation, humor, or challenge (e.g., Befunge, Whitespace)
- Shell & Scripting – Used for automation and system tasks (e.g., Bash, PowerShell)
- Web Languages – Focused on front-end and server-side web development (e.g., HTML, JavaScript, PHP)
