Tell us what’s happening:
Hello, I am trying to figure out why we need parentheses after the arrow in bellow code. Ideas, comments, solutions are very welcome 
Thanx!
P.S. It is my understanding that this kind of unclarities cause much coding problems later on, so I am trying to grasp it early. 
Thanks in advance for your time and effort!
Your code so far
this.setState(state => ({
count: state.count + 1
}));
// why not as bellow?
increment() {
this.setState(state => {
count: state.count + 1
});
```jsx
class Counter extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0
};
// change code below this line
// change code above this line
}
// change code below this line
// change code above this line
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>
<h1>Current Count: {this.state.count}</h1>
</div>
);
}
};
