# 2) Architecture/High Level Design

The component architecture part of a frontend system design refers to the organization and structure of the individual components that make up the user interface of a web or mobile application. These components can include buttons, forms, navigation menus, and other interactive elements.

The component architecture should be designed in a way that allows for easy maintenance and scalability, as well as ensuring a consistent user experience across the application.

One common approach to component architecture is the use of a component library, which is a collection of reusable components that can be easily integrated into different parts of the application. These components should be designed to be flexible and adaptable, allowing for different styles and configurations to be applied as needed.

Another important aspect of component architecture is the use of state management, which is used to manage the data and behavior of components in the application. State management tools such as Redux or MobX can be used to handle updates to the application state and ensure that components are always in sync with the latest data.

Overall, the component architecture of a frontend system design should be well-organized, easy to maintain, and optimized for performance to ensure a smooth user experience.
