how to create react props code example

Example 1: create react component class

class MyComponent extends React.Component{
    constructor(props){
        super(props);
    };
    render(){
        return(
            

              

              	My First React Component!
              
            
        );
    }
};

Example 2: props in react app

/* PASSING THE PROPS to the 'Greeting' component */
const expression = 'Happy';
 // statement and expression are the props (ie. arguments) we are passing to Greeting component

/* USING THE PROPS in the child component */
class Greeting extends Component {
  render() {
    return 
{this.props.statement} I am feeling {this.props.expression} today!
;
  }
}

function Welcome(props) {
  return 
Hello, {props.name}
;
}

const element = ;
ReactDOM.render(
  element,
  document.getElementById('root')
);
