Problem with Pomodoro Clock countdown function!

[corpsist]

Tell us what’s happening:
Can anyone point out the mistakes in my handleClick function that controls the countdown.

1. On clicking the play button more than once the speed of countdown also increases simultaneously.
2. After the end of the Break session, the countdown isn’t going back to the counting the normal Session again.
   Plz help !

handleClick(){
    this.setState({
      running : true
    })
  
    setInterval(function(){
      if(this.state.running ){
      if(this.state.seconds>0){
        this.setState({
          seconds : this.state.seconds - 1
        })
      }
      if(this.state.seconds == 0){
        if(this.state.minutes == 0){
          this.setState({
            timerTitle: 'Break',
            minutes : this.state.breakMinutes,
            seconds : 0
          })
          if(this.state.seconds>0){
            this.setState({
              seconds : this.state.seconds - 1
            })
          }
          if(this.state.seconds == 0){
             if(this.state.breakMinutes == 0){
               this.setState({
                 timerTitle: 'Session',
                 minutes : this.state.sessionMinutes,
                 seconds : 0
               })
               this.handleClick;
             }
            else{
              this.setState({
                minutes : this.state.minutes - 1,
                seconds : 59
              })
            }
          }
        }
        else{
          this.setState({
            minutes : this.state.minutes - 1,
            seconds : 59
          })
        }
      }
     }
    }.bind(this), 1000)
  
}

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

Please use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks are not single quotes.

Everytime I click Play button your code sets up new interval and this causes some weird artefacts. You might want to check if Timer is already running prior to setting an interval
