defs.js is a static scope analyzer and transpiler that converts ES6 block-scoped `const` and `let` variables to ES3-compatible `var` declarations, enabling modern JavaScript syntax in older environments. It's designed for developers who need to write ES6-compliant code but must support ES3 runtimes, such as older browsers or legacy Node.js versions, while also providing linting capabilities for scope analysis.
