To separate domain logic from UI in React components, move business logic out of UI code and into pure functions or non-UI utilities. This keeps presentational components focused strictly on rendering and event handling.

The best way to reduce dependency array bloat in React hooks is keeping component responsibilities minimal and using focused hooks. Applying actionable patterns like the Finger Rule ensures dependencies remain readable and render stability is maintained.

You need a three-layer architecture for your React codebase when components mix domain logic with UI, making code hard to test and maintain. This approach is essential for codebases with hooks, callbacks, modals, and store interactions to reduce high dependencies.

To audit a React component to ensure it only handles UI concerns, check that business logic has been moved into pure functions or hooks. The component should strictly handle rendering and events, keeping its file size under a measurable threshold.

Mixing business logic in React components makes code hard to maintain because it entangles domain rules with UI rendering, causing stale closures and high dependency components. Separating concerns into pure functions and presentational components resolves this.

Yes, you can apply the Finger Rule to manage React hook dependencies and render stability. This actionable pattern guides developers to keep dependency arrays readable and minimal, preventing stale closures and reducing component complexity.
