如果你不想在点击按钮时触发它，它应该在一个效果钩子中，比如：

useEffect(() => {
    performance.mark('performanceStart');

    // Do you state updates here etc.

    requestAnimationFrame(() => {
      performance.mark('performanceEnd');
      performance.measure('performance', 'performanceStart', 'performanceEnd');
      const measure = performance.getEntriesByName('performance')[0];
      console.log(measure.duration);
    });
  }, []);
