🏗️ Architecture

Verion Language consists of four main components:

1. Tokenizer (compiler/tokenizer.js) - Converts source code into tokens
2. Parser (compiler/parser.js) - Converts tokens into an Abstract Syntax Tree
3. Interpreter (compiler/interpreter.js) - Executes the AST directly
4. Transpiler (compiler/transpiler.js) - Converts AST to JavaScript

📖 Examples

The examples/ directory contains sample programs demonstrating all features:

• hello.vl - Hello World
• variables.vl - Variable declarations and math
• functions.vl - Function definitions and calls
• conditionals.vl - If/else statements
• loops.vl - Repeat loops
• complete.vl - All features combined
