repository for polyfills

Polymer 3 uses Javascript modules, the polyfills of babel works well for local proyects but i need them work in codepen 8)

I try to use

ES Module Loader Polyfill

But it did not work out of the box, so I ask in

polymer slack

and Daniel Busłowicz

Help me with a working example 8)

I need a copy in my own repo, so i did not link his files, so download the code and put it here.

I did not own the code, babel and others wrote it, i just have it here for my codepens to work, If some owner wants me to delete them plz notify me 8)
