I really don't agree, as a developer writing predominantly js. It's still pretty standard to compile es6 down to at least es2015 using babel or typescript, meaning js still runs everywhere. I've also literally never met anyone who thinks that callback-structured code is "not a problem". And you can work around issues of "this" and lexical scoping to the point where it isn't as irritating, but it's completely unintuitive to a new js developer, and IMO at least never stops feeling "wrong". There are also a ton of features aside from arrow functions and promises that completely change the way code is written for the better- off the top of my head I use ` string formatting, classes, let/const declarations, and module loading every day.
