## Description

This project is a suite of tools designed to track and visualize the compatibility of JavaScript language features across different execution engines and runtimes. It functions as an ECMAScript compatibility table generator and a runtime support mapper, using a dedicated feature test suite to identify support gaps across various environments.

The system includes a compiler transpilation validator to ensure new language syntax is correctly handled for older target environments. It verifies operational compatibility by executing specific language feature tests within various JavaScript engines and compilers.

The toolset covers the broader surface of web runtime testing and browser compatibility documentation. It transforms raw execution data into structured environment maps and visual matrices that map feature availability against specific platform versions.
