ChettaLang – A Malayalam-Inspired Browser-Based Programming Language & Interpreter

ChettaLang is a Malayalam-inspired programming language that allows users to write code using localized Malayalam keywords. Inspired by BhaiLang, this project was built to make programming more relatable, culturally engaging, and accessible to Malayalam speakers.

Unlike a simple syntax wrapper, ChettaLang is a fully functional browser-based interpreter built entirely with vanilla JavaScript. It includes a custom lexer, parser (AST builder), and interpreter, all running client-side without any backend dependency.

The project is deployed via GitHub Pages, allowing anyone to try the language instantly without installation.

🌟 Features

• ✨ Malayalam-inspired keywords - Code in your language!
• 🚀 Browser-based interpreter - No installation required
• 💻 Interactive IDE - Write, run, and debug instantly
• 📚 Rich examples - Learn from pre-built programs
• 🎨 Beautiful UI - Modern, responsive design
• 🔥 GitHub Pages ready - Deploy in minutes
