Webshim

Webshim is a deprecated modular polyfill-loading library created to help developers use HTML5 features across browsers with inconsistent native support. It was designed around capability detection, meaning it loads only the needed polyfills instead of treating every browser the same. The library was especially useful when older browsers lacked reliable support for modern form controls, media elements, and other HTML5 APIs. It helped front-end developers build more consistent user experiences during a period when browser support varied widely. The project depends on the older JavaScript ecosystem and is not compatible with newer jQuery 3.x workflows. Today, it is best understood as a legacy compatibility tool for older web projects rather than a modern front-end dependency.
