Web Inspector now: - uses classes heavily - uses arrow functions in many places - uses Generators, Proxy, Promise, Symbol, Map, Set - uses destructuring, object literal shorthands, and for..of - uses rest parameters and spread operator - uses plenty of native methods (includes, fill, startsWith, etc) I imagine we could use a Symbol.iterable somewhere, but it doesn't seem important. I think we are quite modernized now. Lets close.
