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
You can roll your own or use a utility library. A simple zero-dependency library would be something like just-group-by [1]. Although I now prefer remeda [2] as it seems to have the best typescript support, especially the strict variants such as `grouBy.strict`.

No Lodash
Tree-shaking doesn't help much when the tree-shaken implementation is so bloated.
Here's the one you referenced, lodash.chunk: https://unpkg.com/lodash.chunk – 140 lines after removing comments and whitespace.
That's pretty small compared to a lot of the lodash utilities. Try spot-checking a few on unpkg.
I prefer angus's `just` utilities: https://github.com/angus-c/just

Snap.js - A competitor to Lodash
I absolutely love this. When I need some Lodash alternative I'll usually reference angus-c/just but I am definitely bookmarking this for next time.

[AskJS] Which JS libraries and packages are currently your favourites?
The just set of utility functions are really nice to use. https://github.com/angus-c/just

/svu - svultimate svelte svutilities
One of my favourite "libraries" are the "just" packages, where each part of the library is it's own simple package with zero dependencies (https://github.com/angus-c/just) so you essentially just npm install the specific thing you want - which is generally a single function.

What is the best memoization library?
If the code should, as you say, be 5 lines, why take on a dependency at all? By doing so, you end up with a catch-all solution that does almost nothing other than JSON.stringify your args, which is extremely poorly optimized to handle many situations, e.g. one of your args is a primitive and the other is a large config object.

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.

Lodash just declared issue bankruptcy and closed every issue and open PR
Very much agreed. The amount of mileage we get from using Spread (literally the ...) alone has been amazing. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... Iteration helpers is shipping soon, that'll be a huge help (async iteration helpers will be delayed for a while). https://github.com/tc39/proposal-iterator-helpers .
In the olden days, I feel like the codebases I worked on needed to use .apply() multiple times a week, to figure out some creative way of invoking functions. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... That's all gone now; I'd take even odds that 50% of my team knows .call and .apply.
Chrome 117 is shipping Object.groupBy() and that's gonna be a huge help in eliminating a lot of the last places we end up using lodash. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

It’s 2023. Start using JavaScript Map and Set
Once this https://github.com/tc39/proposal-iterator-helpers reaches browsers, I'm prob gonna be exclusively using Maps.

Updates from the 95th TC39 meeting
No, probably not. But with iterator helpers, you can do

All JavaScript and TypeScript features of the last 3 years explained
> focus more on improving the terrible JS web API
That's W3C’s job, not ECMA’s.
> Where are all the containers?

> Sorted sets/maps?
Sets and Maps are sorted (by insertion order)
> Why can't I even map an iterator?
It's coming, but someone will likely be exhausted by that addition. https://github.com/tc39/proposal-iterator-helpers

[AskJS] Is JavaScript missing some built-in methods?
Not Generators, but Iterators have a Stage 3 proposal with helpers like these.

Just fighting URLSearchParams and wonder if anyone uses iterators IRL and what I do miss
I guess you are not the only one dealing with this. That’s why there is this proposal https://github.com/tc39/proposal-iterator-helpers So hopefully it will get easier soon. But in most cases you can simply wrap it in Array.from or you can also clone with the spread operator.
