Understanding component-based architecture for UI development...

Component-based architecture breaks down complex user interfaces into smaller, reusable components, improving modularity, reusability, maintenance, and collaboration in UI development. It allows developers to build, maintain, and update large-scale applications more efficiently by creating independent units that can be used across multiple pages or even applications.
