In ReactJS, you can create components using classes or functional components. Although functional components with hooks (useState, useEffect, etc.) are now preferred, class components are still widely used in legacy codebases.

✅ Class Component Example

Here’s how you create a class component in React:

jsx
<h1>Welcome, {this.props.name}!<h1>Lifecycle Demo</h1>;  }}

✅ When to Use Class Components

• When working with older React codebases.

• If you need to manage complex state or lifecycle methods.

• When dealing with legacy libraries that require class components.

✅ Switching to Functional Components

Since React Hooks were introduced in React 16.8, functional components are often used instead of class components.
