What will happen in this class component?
class Demo extends React.Component {
constructor(props) {
super(props);
this.state = { count: 0 };
this.setState({ count: 1 });
}
render() {
return <div>{this.state.count}</div>;
}
}
The component renders 1
The component renders 0
Infinite re-render loop
Error: Cannot call setState in constructor
