Difference between functional and class component

Question

Accepted Answer

Functional components are simpler, stateless, and use functional programming concepts. Class components are more complex, stateful, and use ES6 class syntax.

Functional components are just plain JavaScript functions that accept props as arguments and return React elements.
Class components are ES6 classes that extend from React.Component and can have state and lifecycle methods.
Functional components are easier to read, write, and test.
Class components have access to lifecycle methods like componentDidMount and componentDidUpdate.
Example: Functional component - const Greeting = (props) =>
Hello, {props.name}
; Class component - class Greeting extends React.Component { render() { return
Hello, {this.props.name}
; }}
