Tell us what’s happening:
Everything seems to work. My code matches the “hint” code.
Your code so far
class Dialog extends React.Component {
constructor(props) {
super(props);
}
componentWillUpdate() {
console.log('Component is about to update...');
}
// change code below this line
componentWIllReceiveProps(nextProps){
console.log(this.props, nextProps);
}
componentDidUpdate(){
console.log('Component has updated');
}
// change code above this line
render() {
return <h1>{this.props.message}</h1>
}
};
class Controller extends React.Component {
constructor(props) {
super(props);
this.state = {
message: 'First Message'
};
this.changeMessage = this.changeMessage.bind(this);
}
changeMessage() {
this.setState({
message: 'Second Message'
});
}
render() {
return (
<div>
<button onClick={this.changeMessage}>Update</button>
<Dialog message={this.state.message}/>
</div>
);
}
};
