Prototype-based inheritance is widely supported across modern browsers. However, older browsers (IE < 11) may have inconsistencies or performance issues. core-js (https://github.com/zloirock/core-js) provides polyfills for missing or buggy features, including Object.create() and prototype-related methods. Babel can be configured to transpile modern JavaScript code to older versions, ensuring compatibility. Feature detection using typeof or in operators can be used to conditionally apply polyfills only when necessary.
