About

Core-js is a modular standard library for JavaScript that provides polyfills for ECMAScript up to 2024: promises, symbols, collections, iterators, typed arrays, and proposals.

Modernizr is an open-source feature detection library that identifies browser support for HTML, CSS, and JavaScript features and allows websites to adapt accordingly.

It enables developers to detect supported browser features at runtime, apply progressive enhancement, load polyfills only when required, and provide fallbacks for unsupported features.
