Bind 'this' to a Class Method

// Theory

class MyClass {
  constructor() {
    this.myMethod = this.myMethod.bind(this);
  }

  myMethod() {
    // whatever myMethod does
  }
}

 // Solution
 
class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      text: "Hello"
    };
    this.handleClick = this.handleClick.bind(this);
  }
  
  handleClick() {
    this.setState({
      text: "You clicked!"
    });
  }
  
  render() {
    return (
      <div>
        <button onClick = {this.handleClick}>Click Me</button>
        <h1>{this.state.text}</h1>
      </div>
    );
  }
};
