Emotion vs. React vs. Semantic UI React vs. jscoverage Comparison Chart

Emotion is a performant, flexible CSS-in-JS library designed for writing CSS styles using JavaScript, supporting both string-based and object-based styles while delivering a strong developer experience, complete with source maps, labels, and testing utilities. It offers two powerful usage patterns; a framework-agnostic approach which requires no special configuration yet supports vendor-prefixing, nested selectors, media queries, and class composition through the CSS and CX functions; and a React-optimized variant providing advanced features like the CSS prop for direct styling (similar to the style prop but with support for nested selectors, media queries, and theming capabilities), zero-configuration server-side rendering, native theming, and compatibility with ESLint tooling. Emotion also supports styled-component-like APIs, enabling tag-based or component-based styled elements with dynamic prop-driven styling.

Semantic UI React is the official React integration for Semantic UI. jQuery-free, declarative API, augmentation, shorthand props, sub-components, auto controlled state. jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components.
