core-js is a modular standard library for JavaScript that provides "polyfills"—bits of code that bring modern features to older browsers or environments that don't support them yet. It is the silent engine behind the scenes for millions of websites; when you use the latest JavaScript syntax (like Array.from or Promise.any), core-js is often what makes it work in every browser. In 2026, it remains a critical infrastructure project, supporting ECMAScript features up to the latest 2026 specifications. While users never see it, developers rely on it via tools like Babel or SWC to ensure their code is "future-proof" without breaking for users on legacy devices.
