no-method.js

class StopWatch extends React.Component {
  state = { lapse: 0, running: false };
  handleRunClick = () => {
    const startTime = Date.now() - this.state.lapse;
    setInterval(() => {
      this.setState({
        lapse: Date.now - startTime
      });
    });
    this.setState({
      running: true
    });
  };
