13 };
14 }
15 componentWillMount() {
16 this.intervalID = setInterval(() => this.updateTime(), 1000);
17 }
18 componentWillUnmount() {
19 clearInterval(this.intervalID);
20 }
21 updateTime() {
22 this.setState({

20
21 componentWillMount() {
22 this.intervalID = setInterval(() => this.tick(), 1000);
23 }
24 componentWillUnmount() {
25 clearInterval(this.intervalID);
26 }
