Shameful plug: http://invig.io is a a wrapper around decaffinate, lebab, prettier, eslint, to to squeeze more modernness out of legacy js/coffeescript codebases and make them standardjs.com compliant
I love standardjs.com. It takes an enormous amount of chutzpah to look at jQuery style guidelines, idiomatic.js, AirBnB and every previous JavaScript style guide and declare the name of your own new thing is `${standard} ${languageName}`
That's excellent. Thanks for the recommendation.
