Component

A component is like a LEGO block that can be combined with others to build something larger and more complex.

A button on a website might be a reusable component that can be used in multiple places across the site.

Components allow developers to build software more efficiently by reusing code and ensuring consistency across a system.

Using components can reduce development time, increase code reliability, and make it easier to update and maintain software.

• Use Case 1: Building a user interface where consistent design and functionality are required across different parts of an application.
• Use Case 2: Developing complex software systems where different teams need to work on different parts independently.
• Use Case 3: When updating a feature, as components allow changes to be made in one place without affecting the entire system.

Design components to be as reusable and decoupled as possible; maintain a component library; ensure components are well-documented.

Overcomplicating components; not maintaining consistency across components; poor documentation leading to misused or duplicated components.

Reusability rate, component size, number of dependencies.
