Use state sparingly and only when necessary. State is used to store data that can change over time and is managed by the component itself. However, overusing state can lead to performance issues and make the code harder to maintain. It is important to only use state when necessary and to keep the state as minimal as possible.

One way to minimize the use of state is to use props instead. Props are used to pass data from a parent component to a child component. This allows for better separation of concerns and makes the code easier to reason about. When a child component needs to update its parent component, it can do so by calling a function passed down as a prop.

Another way to minimize the use of state is to use React hooks. Hooks are functions that allow you to use state and other React features in functional components. They provide a way to reuse stateful logic between components and make it easier to manage complex state. Some commonly used hooks include useState, useEffect, and useContext.

// Example of using props instead of state
function ParentComponent() {
  const [count, setCount] = useState(0);

  function handleIncrement() {
    setCount(count + 1);
  }

  return (
    <div>
      <ChildComponent count={count} onIncrement={handleIncrement} />
    </div>
  );
}

function ChildComponent({ count, onIncrement }) {
  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={onIncrement}>Increment</button>
    </div>
  );
}

// Example of using React hooks
function Counter() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    document.title = `Count: ${count}`;
  }, [count]);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
}
