How can I understand 'bind'?

It is a little difficult for me to understand “this.handleClick = this.handleClick.bind(this)”, actually I don’t know what happened after we write this code, anybody can help me with this? And why we don’t use bind when we use 'this.props 'and ‘this.state’? Thanks

  **Your code so far**

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

In essence, it is due to how the keyword this works in Javascript. FCC itself has an excellent article going over the details here
