Better way to handle start/stop

This is just my opinion, but isn’t this the best way to implement the start/stop text?

<button>{this.state.running ? "Stop" : "Start"}</button>

It’s similar to what @jim did, but it doesn’t have the duplicate <button> code.

My question is, did I make a mistake?

You had the right idea!

For your button onClick, use this:

  handleClick () {
    this.setState({ running: !this.state.running });

I know you wrote this 5 months ago, but perhaps other students will see it.

This worked great, thanks Adam!

Yeah. It worked well.

Well never mind, as I kept watching the video, I realized that it would be hard to implement the click handlers this way. :D
