让我来描述一下：
正如您在下面的代码中看到的,我有2个按钮(一个按钮是将电路板的大小更改为10 x 10,另一个是更改间隔的速度).

一切都很好,除了当我点击这两个按钮时,我需要双击才能执行.在第一次点击时,使用Chrome中的React Developer Tool,我可以看到状态包括宽度,高度,速度都会改变,但状态板仍然保持不变.只有在第二次单击后,才会更改电路板状态.

任何人都可以解释原因,并告诉我如何解决？谢谢

这是我的代码的一部分

        return {
             width: 10,height: 10,board: [],speed: 1000,};

    clear: function(width,height) {
