es-compat is a tool for checking JavaScript code compatibility with target browsers and Node.js versions, helping developers ensure their code uses only supported language features. It's particularly useful for projects that either don't use transpilers or need to verify that transpiled code and third-party libraries are compatible with target environments. The tool works by analyzing code against browserslist targets using MDN compatibility data, making it ideal for frontend teams maintaining browser support matrices.
