Rendering propsReact.js 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 <div>{props.render(name)}</div>
}

//Then we can use this component like this:
<div>
  //when using the component we receive the passed values (name) as args here 
  <User render={(name) => <div>{name}</div>} /> 
</div>

Example 2: pass props in react

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