如何在 Visual Studio Code 中运行 JavaScript 代码

在 Visual Studio Code 中运行 JavaScript 代码有以下几种方法：

1. 运行选定代码

选中要运行的代码块。
按 Ctrl + Alt + N (Windows) 或 Cmd + Option + N (macOS)。
这将创建一个文件，其中包含选定的代码块，并将其作为 Node.js 应用程序运行。

2. 使用调试器

打开要调试的 JavaScript 文件。
在菜单栏中，点击 "调试" > "启动调试"（或按 F5）。
这将启动调试会话，允许你在代码执行时设置断点和单步调试。

3. 使用命令行

打开终端窗口（Ctrl + Shift + ~ 或 Cmd + Shift + ~）。
导航到 JavaScript 文件所在目录。
运行以下命令：

<code>node filename.js</code>

其他提示：

确保你的电脑上已经安装了 Node.js。
如果你的 JavaScript 文件中使用 ES6 或更高版本的语法，你需要在 package.json 文件中设置 "type": "module"。
你还可以使用扩展程序来增强 Visual Studio Code 中 JavaScript 的开发体验，例如 JavaScript IntelliSense 和 Live Server。
