## Написать простой счетчик
#### Подсказка 1:
```JSX
class Counter extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0
};
// change code below this line
// Remember the previous challange.
// Bind "this" for each of these three method (increment(),decrement() and reset()).
// change code above this line
}
// change code below this line
// Define these three method here.
// Inside these methods, call "setState()" method to update the data of construtor`s state.
// change code above this line
render() {
return (
Current Count: {this.state.count}
);
}
};
```
## Решение:
```JSX
class Counter extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0
};
// change code below this line
this.increment = this.increment.bind(this);
this.decrement = this.decrement.bind(this);
this.reset = this.reset.bind(this);
// change code above this line
}
// change code below this line
increment(){this.setState({count: this.state.count + 1})}
decrement(){this.setState({count: this.state.count - 1})}
reset(){this.setState({count: 0})}
// change code above this line
render() {
return (
