我是初学者，恐怕我完全糊涂了。
做一个记忆游戏练习，我想从（比如）40个文件夹中随机选择一个3x3的图像网格，当单击一个图像时，随机生成一组9个新的图像 clickCount 在游戏状态下（目标是点击尽可能多的未点击的图片）。也许问题在于我的thinkpad速度慢，但返回带有URL的对象数组的函数耗时太长，以致应用程序可能崩溃（随机数组未就绪）或随机跳过加载时的图像函数调用（希望在添加记分板逻辑之前解决此问题，如下所示）。
我只是从react开始，所以我一直在梳理 suspense , memo 、延迟加载、承诺/异步等。但在我学习的早期阶段，我很难充分理解哪一个适合这种情况。

问我任何你想问的问题如果我不清楚，我只是完全停留在这一点上，并将感谢一些意见（对概述的问题或任何其他我做了错事）。
非常感谢。
