JavaScript Web Developers often encounter challenges ensuring that web applications function consistently across different browsers and their various versions.

To overcome these challenges, developers frequently use polyfills, transpilers like Babel, and thorough testing on multiple browsers and devices. Collaborating with QA teams and staying updated on browser release notes are also important strategies to maintain compatibility and deliver a seamless user experience.
