class Counter extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      count: 0
    };

this.decrement = this.decrement.bind(this);
 this.increment = this.increment.bind(this);
this.reset = this.reset.bind(this);

  }

increment(){
  this.setState(state => ({
count: state.count + 1
  }))
}

decrement(){
  this.setState(state => ({
count : state.count - 1
  }))
}

reset(){
  this.setState(({
    count : 0
  }))
}
  render() {
    return (
      <div>
        <button className='inc' onClick={this.increment}>Increment!</button>
        <button className='dec' onClick={this.decrement}>Decrement!</button>
        <button className='reset' onClick={this.reset}>Reset</button>
