   import create from 'zustand';

   const useStore = create((set) => ({
     count: 0,
     increase: () => set((state) => ({ count: state.count + 1 })),
     decrease: () => set((state) => ({ count: state.count - 1 })),
   }));

   import React from 'react';
   import useStore from './store';

   function Counter() {
     const { count, increase, decrease } = useStore();
     return (
       <div>
         <h1>{count}</h1>
         <button onClick={increase}>Increase</button>
         <button onClick={decrease}>Decrease</button>
       </div>
     );
   }

   export default Counter;

This approach drastically reduces the number of rendered DOM nodes, improving performance when dealing with large datasets.

• Avoid unnecessary re-renders: Use React.memo, useMemo, and useCallback to prevent components from re-rendering unnecessarily.
• Use Lazy Loading: Defer loading of components and assets until they are actually needed to improve the initial load time.
• Optimize Large Lists: Use windowing techniques to render only the visible portion of large lists, reducing the rendering workload.
• Profile and Measure: Use React's built-in profiling tools to identify performance bottlenecks and optimize where needed.
