Javascript Programming Tutorials, Guides & Best Practices

Zustand is a small, fast, and scalable state management solution for React applications. Developed by the creators of Jotai and React-spring, Zustand aims to provide a minimalistic API based on hooks, eliminating the need for boilerplate code and context providers.

Key Features:

import React from 'react';

const ChildComponent = React.memo(({ name }) => {
  console.log('Rendering ChildComponent');
  return <div>Hello, {name}!</div>;
});

function ParentComponent() {
  const [count, setCount] = useState(0);

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

In this example, ChildComponent only re-renders if the name prop changes, even when the parent component re-renders due to state changes.
