es-constants is a JavaScript library that provides an ES-spec-compliant shim/polyfill/replacement for Math and Number constant values, working as far back as ES3. It's designed for developers who need to ensure consistent behavior of mathematical constants across different JavaScript environments, particularly when supporting older browsers or runtimes.
