How does CSS-in-JS compare to traditional CSS?

What are the main differences between CSS-in-JS and traditional CSS?

CSS-in-JS allows you to write CSS directly within your JavaScript files, promoting component-scoped styles. Traditional CSS, on the other hand, uses separate .css files that apply styles globally.

What are the advantages of using CSS-in-JS?

Some advantages include better encapsulation of styles, dynamic styling based on props, and easier maintenance as styles are co-located with components.

Are there any downsides to using CSS-in-JS?

Yes, potential downsides include increased bundle size, reliance on JavaScript for styling, and possible performance issues if not managed properly.

Which libraries are popular for CSS-in-JS?

Popular libraries include styled-components, Emotion, and JSS. Each has its own features and benefits.

When should I choose traditional CSS over CSS-in-JS?

You might prefer traditional CSS for larger projects with a lot of existing styles, or when you want to keep styles separate from JavaScript for better performance.
