WHAT IS POLYFILL.IO?

It's a service which accepts a request for a set of browser features and returns
only the polyfills that are needed by the requesting browser.


WHY DO I NEED IT?

There are lots of differing browsers and browser versions in use throughout the
world, each one has a slightly different set of features to the rest. This can
make developing for browsers a difficult task. The latest versions of the
popular browsers can do lots of things which older browsers can not – but you
may still have to support the older browsers. Polyfill.io makes it simpler to
support differing browsers by attempting to recreate the missing features with
polyfills: You can make use of the latest and greatest features in browsers
which support them, and in those that do not.
