<Greeting statement='Hello' expression={expression}/> // 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 <h1>{this.props.statement} I am feeling {this.props.expression} today!</h1>;

react props

By Eitan Feinberg on Jan 09, 2021

Props is a way to transform data from one component to another.
<Ball numbre = '1'/>
 //IN component
  {this.props.numbre} // in html is 1
