In a complex React application with various interconnected components, you want to avoid unnecessary re-renders while sharing state and logic. Which React pattern would be most suitable to achieve this objective?

  • Component Composition with PureComponent or shouldComponentUpdate
  • React Hooks (useMemo, useCallback)
  • Redux-Saga
  • Render Props
To avoid unnecessary re-renders while sharing state and logic in a complex React application, React Hooks like useMemo and useCallback are most suitable. These hooks allow you to memoize values and functions, respectively, ensuring that components only re-render when necessary. While Render Props, Redux-Saga, and Component Composition with PureComponent or shouldComponentUpdate have their uses, React Hooks provide a more fine-grained control over re-renders in a complex interconnected component environment.
