ponyfill

Ponyfill is an explanatory project that defines and promotes a side-effect-free alternative to traditional polyfills. A ponyfill implements the behavior of a standard feature without modifying the native environment or pretending to be the built-in API. In JavaScript, this means importing and calling a normal module instead of patching globals such as Object, Array prototypes, or window. The approach reduces conflicts when specifications change or when multiple libraries implement the same feature differently. The repository also shows that the idea can extend beyond JavaScript to HTML and CSS techniques. Its examples compare ponyfills directly with polyfills and emphasize explicit, predictable usage. It is best understood as a reference and design pattern rather than a standalone runtime package.
