class Hello extends React.Component { constructor(props) {  super(props);  this.state = {count: props.initialCount}; } // ...}
4. Automatic Binding
Class SayHello extends React. Component {constructor (props) {super (props); this. state = {message: 'Hello! '}; // This line is very important this. handleClick = this. handleClick. bind (this);} handleClick () {alert (this. state. message);} render () {// Because 'this. handleclick' is bound, we can use it as an event handler. return (<button onClick = {this. handleClick}> Say hello </button> );}}
