Why doesn’t this code work?

  render() {

    
   return (
      <div className="App container">
        <button className="btn btn-primary mt-4" onClick={changeState}>Working</button>
        <div className="myState">
          <p>This state of my app {this.state.myState}</p>
        </div>
      </div>
    );
  }


  changeState(){
    this.setState({myState: 'working'})
 }

}

export default App;

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Can’t remember off the top of my head, so excuse me if I’m wrong, but shouldn’t the call to changeState in the onClick atrribute be this.changeState?

onClick={this.changeState}
