TC39: Add Object.groupBy and Map.groupBy
Global iterator type is coming: https://github.com/tc39/proposal-iterator-helpers
But a method named `groupBy` on iterators traditionally means a different thing: https://github.com/tc39/proposal-array-grouping/issues/51#is...
Global iterable type it's too late for, since there's many extant iterables in the language and on the web which don't have it in their prototype chain and can't reasonably be changed.

At the end of the day, it comes down to whether browser vendors are willing to ship the feature even though it breaks said websites, and they do have visitor data to back those decisions. If the rule was "never break any website ever", you'd be able to block proposals you don't personally like by crafting a website that "gets broken" by that proposal.
At least in the array grouping proposal, they did evaluate amount and popularity of possibly breaking sites, before eventually renaming the method from .groupBy to .group

Handling dates in JavaScript with Tempo
Even with the initial pitfalls of JavaScript dates, the ecosystem managed to tackle those challenges with good libraries. Some use the native JavaScript date while others have instead created their own robust tools to make up for the quirks JavaScript dates might have. With the JavaScript Temporal API about to roll out, working with dates and time in JavaScript will only improve.
