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.

Can Protractor and Karma be used together?
If Protractor is replacing Angular Scenario Runner for E2E testing, does that mean I will still be able to use it with Karma as my E2E testing framework ?
