Hi. I made Easylang to help beginners get started with programming. It is open source. https://github.com/chkas/easylang Why I think Easylang is for beginners better than Python. https://easylang.online/blog/easyl_pyth.html UPDATE: The posted link goes directly to the beginner tutorial.

The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…
