import React from 'react';

const customUseState = (initialState) => {
  let state = initialState;

  const setState = (newState) => {
    state = newState;
    // Trigger a re-render
    // (This is a simplified version; React handles re-renders differently.)
    render();
  };

  return [state, setState];
};

const App = () => {
  // Using the custom useState hook
  const [count, setCount] = customUseState(0);

  const handleIncrement = () => {
    setCount(count + 1);
  };

  const handleDecrement = () => {
    setCount(count - 1);
  };

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={handleIncrement}>Increment</button>
      <button onClick={handleDecrement}>Decrement</button>
    </div>
  );
};

// This is a simplified render function just for illustration purposes.
// In a real React app, the rendering is handled by React's reconciler.
const render = () => {
  ReactDOM.render(<App />, document.getElementById('root'));
};

// Initial render
render();
