CSS in JS: Is it worth the hype
summary
Styled-components inlines critical CSS to avoid render blocking but Webpack can produce the same effect; a test with four button variants measures 3.4s vs 3.5s vs 3.6s to first meaningful paint while scripting time grows substantially for CSS-in-JS. Collocated styles balloon component files, lack source maps and produce unreadable class names unless Babel plugins add meaningful prefixes or CSS namespaces. Props enable dynamic styles but require complex JS conditionals so props are dangerous; atomic design, BEM or a HOC-to-BEM approach keeps things debuggable and lets components share logic with React Native.
