In web development, a polyfill (or polyfiller) is downloadable code which provides facilities that are not built into a web browser. It implements technology that a developer expects the browser to provide natively, providing a more uniform API landscape. For example, many features of HTML5are not supported by versions of Internet Explorer older than version 8 or 9, but can be used by web pages if those pages install a polyfill.^[1] Webshims^[2] and HTML5 Shivs are related concepts.
