The CanMatch interface is a part of Angular’s routing mechanism that enables conditional route matching. It provides a way to define guard logic that runs before the router tries to activate a route. If all CanMatch guards return true, the router proceeds with navigation to the route. If any guard returns false, the route is skipped for matching, and the router evaluates other route configurations.

The Core Challenge of Scaling CSS

As applications evolve, managing styling consistently becomes even harder. Web projects often face issues like:

— Inconsistent UI elements: Without a unified system, different pages or features can drift apart visually.
— Hard-to-maintain styles: Styling becomes scattered and unorganized, making future changes tedious and error-prone.
— Difficulty in updating themes or branding: Modifying a color or spacing may involve updating hundreds of individual styles.

Before we start the comparison, let’s briefly define Angular and React:

- Angular: A full-fledged front-end framework developed and maintained by Google. It is a complete solution for building large-scale applications, offering built-in tools for everything from routing to state management.

- React: A JavaScript library created by Facebook for building UI components. Unlike Angular, React focuses on the view layer only, offering flexibility to developers by allowing them to choose other libraries and tools for state management, routing, and more.
