我正在努力让我的 vscode 正常工作。它弹出这个错误。“无法开始调试。项目系统提供的启动选项字符串无效。无法确定调试器的路径。请指定无法开始调试。项目系统提供的启动选项字符串无效。无法确定调试器的路径。请指定“MIDebuggerPath”选项。选项。”
代码应该可以正常工作,但是我一定缺少一些东西,而且我在 youtube 教程中的研究并不是很有帮助。

我正在尝试在我的 JS 代码中使用严格模式"use strict";
当我保存文件时,Prettier 将代码格式从"use strict"改为('use strict');
据我所知,这意味着严格模式尚未初始化。我在网上找不到其他人谈论这个问题,所以想知道是否有人可以阐明这个问题?
我对集合进行了分组,并使用 each() 函数对其进行迭代。在每个函数中,我想将元素添加到某个数组中。但它不起作用。知道吗?
