Since this is from 2017, isn't the year missing in the title? When I initially saw the submission, for a moment I thought all the struggles I had some weeks ago had been solved... :-)
I mean, they have been solved. With the exception of String#matchAll (which is currently a Stage 3 proposal), all these features are part of ES2018 and shipping in Chrome. Other browsers implement some of them already and are working on shipping more.
