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.

Front-end Guide
As you might have realized by now, the front end ecosystem is saturated with tools, and unsurprisingly, tools have been invented to partially solve some of the problems with writing CSS at scale. "At scale" means that many developers are working on the same large project and touching the same stylesheets. There is no community-agreed approach on writing CSS in JS at the moment, and we are hoping that one day a winner would emerge, just like Redux did, among all the Flux implementations. For now, we are banking on CSS Modules. CSS modules is an improvement over existing CSS that aims to fix the problem of global namespace in CSS; it enables you to write styles that are local by default and encapsulated to your component. This feature is achieved via tooling. With CSS modules, large teams can write modular and reusable CSS without fear of conflict or overriding other parts of the app. However, at the end of the day, CSS modules are still being compiled into normal globally-namespaced CSS that browsers recognize, and it is still important to learn and understand how raw CSS works.

Why are "CSS classes generally better for performance than inline styles." ~ from react docs
There are a myriad of CSS-in-JS tools, many of which are zero-runtime giving you all the benefits of authoring in a single file without the drawbacks of inline styles. That's how I prefer to do my CSS with React anyway... Vanilla Extract and/or Linaria are my current favorites.

Why was CSS-In-JS ever a thing?
One thing I think you're really missing is what the output is of CSS-in-JS. There are tens of CSS-in-JS frameworks that can output anything from: CSS Module like classes (Linaria, Vanilla Extract), Atomic Classes (StyleX, PreStyle), to the more traditional (Styled Components, Emotion) many with zero runtime cost (ie no JS bloat). That's why I say CSS-in-JS is primarily about developer experience... the output can often be whatever you want it to be.

A recruiter asked me this.
React is pretty much its own language at this point. With J/TSX. Not even CSS is immune to react's approach of "what everything was proprammatically generated divs?", case and point https://www.styletron.org

Tailwind CSS v3
Some technical thoughts as someone who could care less about fanboyism:
- One point where atomic CSS frameworks are supposed to shine over conventional CSS is bundle size, since they (at least the good ones) compile to only a single rule for any used value, rather than potentially repeating rules for semantically different classes.
- Another point where atomic CSS frameworks shine is just sheer volume of banging code out. When the bulk of your output is visual, mastering tools based on shorthands like tailwind, emmet, etc can feel very productive.
- Purely atomic CSS frameworks can make some workflows more difficult, e.g. by having too granular call sites and not allowing "let's see what happens to the overall theme if I do this design change" iterative style of work, or because workflows that edit CSS on the fly via browser devtools can no longer be used to limit impact within semantic lines (e.g. "I want to change padding only on buttons, without breaking everything else that happens to depend on the same padding value"). There are both design-oriented and debugging-oriented workflows that are affected in similar ways.
- You generally don't get visual regressions at a distance w/ atomic CSS. This matters at organizations where desire for pixel precision and simultaneously fickle design teams are the norm. But conversely, "can we just change the font size to be a bit bigger across the site" can often run into issues of missed spots. On a similar note, designs may become inconsistent across a site over time due to the hyper local nature of atomic CSS oriented development.
- Custom rules may as well be written in APL[0]; they usually aren't documented and it takes a "you-gotta-know-them-to-know-them" sort of familiarity to be able to work with them (or get back to them after a while).
- There are some tools that mix and match atomic CSS with other paradigms. For example, styletron[0] can output atomic CSS for the bundling benefits, but looks like React styled components from a devexp perspective, and has rendering modes that output traditional-looking debug classes for chrome devtool oriented workflows.
The main theme to be aware of: proponents rarely talk of maintenance, so beware of honeymoon effect. Detractors often omit that traditional CSS (especially at scale) also requires a lot of diligence to maintain. So think about maintenance and how AOP[1] vs hyperlocal development workflows interact with your organization's design culture.

5 React.js UI Component libraries.
It is created, managed, and utilized by Uber. It includes a wide range of attractive components, with accessibility as the top focus. It is quick since it is built with the Styletron engine. Style overrides can be used to tweak themes, but in my experience, I've never required them because the design vibe they're trying for is precisely what I want.
