Advanced React Patterns

React provides several patterns that help you write more maintainable and reusable code.

Compound Components

Compound components allow you to express relationships between components implicitly.

function Select({ children }: { children: React.ReactNode }) {
  const [value, setValue] = useState('');
  return (
    <SelectContext.Provider value={{ value, setValue }}>
      {children}
    </SelectContext.Provider>
  );
}

function Option({ value, children }: { value: string; children: React.ReactNode }) {
  const context = useSelectContext();
  return (
    <div onClick={() => context.setValue(value)}>
      {children}
    </div>
  );
}

Render Props

Render props allow you to share logic between components.

Control Props

Control props give consumers full control over component state.

Conclusion

These patterns are essential for building robust React applications.
