CSS-in-JS
CSS-in-JS is a styling approach that allows developers to write CSS directly within JavaScript code, typically using JavaScript objects or template literals. It enables scoped styles, dynamic styling based on props or state, and better integration with component-based architectures like React. This method often eliminates the need for separate CSS files and reduces class name conflicts.
Developers should use CSS-in-JS when building modern web applications with frameworks like React, Vue, or Angular, as it provides scoped styling that prevents global CSS conflicts and supports dynamic theming. It's particularly useful for large-scale projects where maintainability and component isolation are priorities, and when leveraging JavaScript's power for conditional or runtime styling.
