Explainer

Specification

https://github.com/whatwg/html/pull/9195 

Summary

customElements.getName() returns the tag name of the given custom element definition.

Blink component

Blink>HTML>CustomElements 

Motivation

Currently there is no way to get the local name of a custom element without instantiating the instance and checking the localName property. This new method allows querying the customElementRegistry to discover the localName of a definition without creating an instance.
