props react component code example

Example 1: render props

//Render props are functions that are passed to props as values
const User = (props) => {
	const [name, setName] = useState('John')

	//we pass values to prop-function as args
	return 
{props.render(name)}
}

//Then we can use this component like this:

  //when using the component we receive the passed values (name) as args here 
   
{name}
} /> 

Example 2: props in react app

/* PASSING THE PROPS to the 'Greeting' component */
const expression = 'Happy';

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

}

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