Thanks. It sounds like subclassing built-ins is where transpilers hit a hard wall. Other syntactic features of es6 can be transpiled.

This page lists features from es6 (and newer versions linked at the top) along with compliance to the spec. First column is the current browser, second is babel+corejs polyfills.

Overall, babel gets about 70% of the way there.
