const sleep = () => {
    const start = new Date().getTime();
    while (new Date().getTime() - start < 5000) {

    }
  };

运用

   const sleep = () => {
    const start = new Date().getTime();
    while (new Date().getTime() - start < 5000) {
    }
  };

 const stopRecording = async () => {
      iatWS.current.send(JSON.stringify({ end: true }));
      sleep();// 5秒钟之后才开始运行后面的逻辑
      clearWS();

  };

在某个时刻取消5秒阻断

const [lastFrameEnable, setLastFrameEnable] = useState(false);

const sleep = () => {
    const start = new Date().getTime();
    while (new Date().getTime() - start < 5000 && lastFrameEnable === false) {

    }
 };

// 在某个时刻取消5秒阻断逻辑
setLastFrameEnable(true);
