Polyfill Service - the lazy way

Polyfills are only loaded when they are needed.
Initial 2Kb to polyfill a lot of Stuff.

Let's assume that your browser does not support the function "String.prototype.at".

> ['a','b','c'].at(-1); // accessing  [].at immediatel loads the polyfill
> 'c'

Ussage

Add this script on the top of your page:

<script src="https://cdn.jsdelivr.net/gh/nuxodin/[email protected]/mod.min.js"></script>

done!

How it works

To every polyfillable property, the scripts adds a getter which synchronously loads the corresponding polyfill.
Of course, we all know that blocking xhr-requests is not nice.
Therefore, the url to the script that should be added to the page is given in the console.

Any help is greatly appreciated.
