import React, { Component } from 'react'; class Counter extends Component { constructor(props) { super(props); this.state = { count: 0 }; } incrementCount() { // TODO: Increase the count state by 1 } render() { return ( <div> <p>Count: {this.state.count}</p> <button onClick={this.incrementCount}>Increment</button> </div> ); } } export default Counter; In the code above, how can we increase the value of the count state by 1 when the user clicks the "Increment" button?
