Separating Business Logic from UI Components in React 18

Separating business logic from UI components brings several advantages to your React applications:

• Code Reusability: When business logic is isolated, it becomes easier to reuse components across different parts of the application or even in other projects.
• Testing: Testing becomes more straightforward as you can write unit tests for the business logic independently from the UI components. This improves test coverage and overall code quality.
• Readability and Maintainability: Decoupling business logic from UI components results in cleaner and more maintainable code. It becomes easier to understand the responsibilities of each part of the application.
• Scalability: As your application grows, separating concerns allows developers to work on different parts of the codebase simultaneously without conflicts.

With React 18, two key features empower developers to separate business logic effectively:

React Hooks React Hooks

introduced in React 16.8, provide a way to use state and other React features without writing class components. With hooks like useState and useEffect, developers can encapsulate business logic and reuse it across components.

Suspense with Concurrent Mode

React 18 brings improvements in Concurrent Mode and Suspense. Concurrent Mode allows React to work on multiple tasks simultaneously, providing better performance. Suspense enables declarative data fetching and code splitting, making it easier to handle asynchronous operations in your components.
