CSS-in-JS: A Front-End Development Technique

CSS-in-JS is a front-end development technique that integrates CSS code directly into JavaScript to overcome certain limitations of traditional CSS. This approach allows for more dynamic and modular style management, using libraries such as styled-components or emotion. The advantages include scoping styles to components, thus reducing style conflicts, and the ability to manipulate styles via JavaScript variables. However, this method can lead to an increase in the size of JavaScript files and increased complexity in style management.
