Node itself needs to better enable some of these. Off hand, I am aware that much of Intl was still flaky in Node into much too recently despite being rock solid in browsers for a lot longer. This is an area where Deno competition seems to be helping. Also, related to Intl replacing tons of code, Moment.js has this disclaimer up top of its README and npmjs.org listing today: > Moment.js is a legacy project, now in maintenance mode. But this is not big or bold enough and it is amazing how many projects still rely on a legacy package like this, which is huge because it bundles its own Intl replacement because it predates Intl. (Please use Luxon or date-fns or Intl.DateTimeFormat directly in 2022 rather Moment.js.)
