How to use the react-addons-perf.printOperations function in react-addons-perf

handleStop() {
    Perf.stop();
    const measurements = Perf.getLastMeasurements();
    console.log('Inclusive');
    Perf.printInclusive(measurements);
    console.log('Exclusive');
    Perf.printExclusive(measurements);
    console.log('Wasted');
    Perf.printWasted(measurements);
    console.log('DOM');
    Perf.printOperations(measurements);
  }

printOperations = () => {
    const lastMeasurements = Perf.getLastMeasurements();

    Perf.printOperations(lastMeasurements);
  };

stopPerf() {
    this.setState({
      idle: true
    });
    Perf.stop();
    Perf.printOperations();
    Perf.printWasted();
  }

setTimeout(() => {
        Perf.stop();
        const measures = Perf.getLastMeasurements();
        Perf.printWasted(measures);
        Perf.printOperations(measures);
      }, 0);
    }

printOperations = () => {
    const lastMeasurements = Perf.getLastMeasurements();

    Perf.printOperations(lastMeasurements);
  };
