## Description

Boa is a high-performance JavaScript engine and parser designed to execute JavaScript code and analyze source code structure. It functions as a runtime environment for executing scripts to automate tasks or process data, providing both a command-line JavaScript interpreter and a tool for converting source code into abstract syntax trees.

The engine is capable of compiling to WebAssembly, allowing the runtime to be deployed and executed within web browser environments. It includes an interactive read-eval-print loop for real-time logic testing and snippet execution via a terminal.

The system covers comprehensive syntax analysis and script execution, including the ability to export parsed code structures for structural analysis and debugging.
