How do I choose between CSS-in-JS and CSS preprocessors?

I'm trying to decide between using CSS-in-JS and CSS preprocessors for my project. Any advice?

Both CSS-in-JS and CSS preprocessors have their advantages. CSS-in-JS allows for dynamic styling and scoped styles, while preprocessors like SASS or LESS offer powerful features like nesting and variables. What are your project requirements?

I need something that works well with React and allows for component-level styling.

In that case, CSS-in-JS might be a better fit. Libraries like styled-components or Emotion integrate seamlessly with React and provide a great developer experience.

What about performance? Is one better than the other?

Performance can vary based on implementation. CSS-in-JS can introduce runtime overhead, but it can also optimize styles for the components in use. Preprocessors compile to static CSS, which can be more performant in some cases. It depends on your specific use case.

Thanks! That helps a lot. I'll consider using CSS-in-JS for my React app.
