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.

If Web Components are so great, why am I not using them?
Now, every time we read `offsetHeight`, the browser sees that it has a scheduled DOM modification to apply, so it has to apply that first, before it can return a correct value.
This is the reason that libraries like fastdom (https://github.com/wilsonpage/fastdom) exist - they help ensure that, in a given tick, all the reads happen first, followed by all the writes.
That said, I suspect even if you add a write followed by a read to your `while(1)` experiment, it still won't actually render anything, because painting is a separate phase of the rendering process, which always happens asynchronously. But that might not be true, and I'm on mobile and can't test it myself.

Performance tips for JavaScript Game Developers
For more information on how and why this works, and a more robust and complete implementation, check out the FastDom library: https://github.com/wilsonpage/fastdom - note that you might not need this particular optimization if you're using a rendering framework, which should already be doing these sorts of optimisations for you.

This course focused on Web Components via Lit. I think we spent a single week (two classes) learning the foundations of web development. Never taught us a single line of HTML, told us to google CSS, and spent that first week showing us what JavaScript does. Personally wish we spent some more time understanding the foundations, but even if I don't know exactly what I am doing... I have been able to accomplish some great stuff.

I've created yet another JavaScript framework
That is the reason why I experiment with the TiniJS framework for a while. It is a collection of tools for developing web/desktop/mobile apps using the native Web Component technology, based on the Lit library. Thank you the Lit team for creating a great tool assists us working with standard Web Component easier.

What We Need Instead of "Web Components"
actually, looking at it (https://lit.dev/), i do exactly that.
I also define a `render()` and extend my own parent, which does a `replaceChildren()` with the render. And, strangely, I also call the processor `html`
I'll still stick with mine however, my 'framework' is half-page of code. I dislike dependencies greatly. I'd need to be saving thousand+ lines at least.
Here, I don't want a build system to make a website; that's mad. So I don't want lit. I want the 5 lines it takes to invoke a dom parser, and the 5 lines it takes do define a webcomp parent.

Web Components Aren't Framework Components
I rather like https://lit.dev/ for web components so far.
For the reactivity stuff, you might want to read https://frontendmasters.com/blog/vanilla-javascript-reactivi... - it shows a bunch of no-library-required patterns that, while in a number of cases I'd much rather use a library myself, all seems at least -basically- reasonable to me and will probably be far more comprehensible to you than whatever I'd reach for, and frameworks are always much more pleasant to approach after you've already done a bunch of stuff by banging rocks together first.

Web Components Eliminate JavaScript Framework Lock-In
I work on Lit, which I would hesitate to call a framework, but gives a framework-like DX for building web components, while trying to keep opinions to a minimum and lock-in as low as possible.
It's got reactivity, declarative templates, great performance, SSR, TypeScript support, native CSS encapsulation, context, tasks, and more.
It's used to build Material Design, settings and devtools UIs for Chrome, some UI for Firefox, Reddit, Photoshop Web...

HTML Web Components
I am more a fan of the augmented style because it doesn't entrap you in dev lock-in to platforms.
The problem with frameworks, especially web frameworks, is they reimplement many items that are standard now (shadowdom, components, storage, templating, base libraries, class/async, network/realtime etc).
If you like the component style of other frameworks but want to use Web Components, Google Lit is quite nice.
Google Lit is like a combination of HTML Web Components and React/Vue style components. The great part is it is build on Web Components underneath.

Web Components Will Outlive Your JavaScript Framework
From the comments I see here, it seems like people expect the Webcomponents API to be a complete replacement for a JS framework. The thing is, our frameworks should start making use of modern web APIs, so the frameworks will have to do less themselves, so can be smaller. Lit [0] for example is doing this. Using Lit is very similar to using React. Some things work different, and you have to get used to some web component specific things, but once you get it, I think it's way more pleasant to work with than React. It feels more natural, native, less framework-specific.
For state management, I created LitState [1], a tiny library (really only 258 lines), which integrates nicely with Lit, and which makes state management between multiple components very easy. It's much easier than the Redux/flux workflows found in React.
So my experience with this is that it's much nicer to work with, and that the libraries are way smaller.
