Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Snap.js - A competitor to Lodash
They are coming out with array.group() soon, which is supposed to also fulfil the use-case of partitioning :) - https://github.com/tc39/proposal-array-grouping.

I'm also looking forward to map.emplace() and arr.group() and iterator helpers.

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

No Lodash
> The API matters, and readability matters.
Exactly, lodash should be part of the language. https://github.com/mlajtos/es1995

> It made the decision to extend prototypes. In hindsight, a huge mistake.
I think it was a mistake at the time, but I still believe prototypal inheritance is pretty great idea. And JS desperately needs standard library, which IMO should extend built-in prototypes, so the language would be more coherent. ES1995 [0] was a funny take on this direction, but people (mainly non-JS people) would like to seriously use it. Go figure.

Thanks! I think we share a few aesthetic ideals :) I really like your work on L1 and New Kind of Paper, and just noticed ES1995 – if only it was true…
