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.

Why Does 'Is-Number' Package Have 59M Weekly Downloads?
Ridiculous as it may be, my guess is that provides a unified way of number checking while avoiding the pitfalls or crazy consequences which could arise from divide-by-zero[1], which I guess might prevent less-experienced folks from tripping up on some of the Javascript gotchas? I'm not really sure. That being said, I have seen those package dependencies in some serious stuff.
Do I agree? I'm not really sure to be honest. Probably not.

Weekly downloads of npm is-odd package
it gets worse: https://github.com/i-voted-for-trump/is-odd/blob/master/index.js

my first pull request got merged in a 2k stars project
So it disappeared and node apps stop building and it was a huge fiasco getting it restored. Just for reference, https://github.com/i-voted-for-trump/is-odd is a current fork of it and it has 34M downloads.

/* This post is a dig at Elon Musk who allegedly ranked employees by the number of lines they wrote. I then added some obviously made up code to hammer home the point that line counts don't always indicate good employees. I also added this 300 character title in case Reddit ranks by title length. */
Checks of this extensiveness would be mad for such a simple library. I mean, who would use a library with that extensive checks?

Vendor by Default (2021)
I think that this approach would cut down the amount of JS dependencies significantly. Things like is-even and is-odd come to mind. You don't want another leftpad or colors.js to happen to you and minimising dependencies is the most effective strategy to accomplish that.
So many leaf dependencies I've looked into are no more than a Stackoverflow answer in a JS file accompanied by six or seven metadata files (package.json + typescript files + linter config + readme + git config + ...). This file: https://github.com/i-voted-for-trump/is-odd/blob/master/inde... is downloaded over 400000 times per week (https://www.npmjs.com/package/is-odd) and while I don't have anythimg against the author for publishing a helpers function, I don't see why I would expose my project to risking a supply chain attack for something so minor. Here's another, with millions of downloads: https://github.com/inspect-js/is-date-object/blob/main/index...
I know that these are all downloaded so ofyen because theyre dependencies of dependencies but I'd appreciate it if bigger libraries would provide a vendored version of their packages that just collects these microdependencies instead of wasting npm's time by making it manage these tiny helper files. Don't vendor stuff like React or Vue or whatever framework you prefer but for the love of God don't add a dependency for 50 lines of code. Sometimes copy/paste is the right solution.

Oops!
I started reading your comment curious about the source code. But I finished reading your comment only more curious. So I went to GitHub's "is-odd" and I've come back to give everyone *is-odd'*s source code in it's entirety. And here it is:

The Monad Invasion - Part 2: Monads in Action!
You probably noticed that .SetName() returns a Either. You may have come across Unit in libraries like MediatR or Language-Ext. It's a simple construct representing a type with only one possible value. We use it as a placeholder for operations that do not return a value but may return another state. In our example, .SetName() is a Command that does not return a value but may fail. Therefore, the monad Either carries two possible states: Right (without value) or Left (with an Error).

Easiest way to build the fastest REST API in C# and .NET 7 using CQRS
I gave it a go and I was impressed how easy and fast it was to set it all up. Since I'm not a big fan of REPR pattern almost all my projects are using CQRS pattern with a help of MediatR ](https://github.com/jbogard/MediatR) I immediately started going over something similar that Fast Endpoints offer which is a command bus.

MVVM Question: How do you manage the interaction between Model and ViewModel?
I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.

Async Methods after setting a property.
If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.

I don't get why I should use Redux
What people really want is to design the logic of an app independently from the component hierarchy. That means you need to store state somewhere other than the components and you need to dispatch events that are not attached to the component hierarchy. Also, a one way data flow has well known benefits as described by things like CQRS, RabbitMQ, and MediatR.
