Polymer 2.x Cheat Sheet - Extending an element #68

Closed rene-lindner-isw closed 7 years ago

Found your Cheat Sheet while looking for an solution to extend iron-ajax.

Tried extends customElement.get('parent-element'), but got an error that customElement does not exist. Shouldn't it be extends window.customElements.get('parent-element') instead?

Thanks for the sheet, helped me alot :)
