@Mitanshu07 from your screen grab you haven’t written any code
the challenge wants you to render the child component welcome in the parent component App then pass a property to it . Finally you access this property in the child component placing it within the strong tag, remember as this is a class component you must prefix with ‘this’ when accessing prop value
Illustration
class Main extends React.Component {
constructor(props) {
super(props)
}
render(){
return (
<div>
<Child name = "a string value" />
</div>
)
}
}
class Child extends React.Component {
constructor(props) {
super(props)
}
render(){
return (
<div>
<p> {this.props.name}</p>
</div>
)
}
}
