如何确定我的React Native应用程序是否是JavaScript代码的调试或发布版本？

I'd like to add some debug-only UI to my React Native app, but I can't find any equivalent of RCT_DEBUG or RCT_DEV compile-time flags in the JavaScript environment. Is there one?

我想在我的React Native应用程序中添加一些仅调试的UI，但我在JavaScript环境中找不到任何等效的RCT_DEBUG或RCT_DEV编译时标志。有吗？

Use case: I want to add a status bar that shows the number of HTTP requests initiated by my app. Obviously this is not part of a shipping app, but it would help me check my work while in development and testing.

使用案例：我想添加一个状态栏，显示我的应用程序发起的HTTP请求数。显然这不是一个发货应用程序的一部分，但它可以帮助我在开发和测试中检查我的工作。

if (__DEV__) {
    console.log('I am in debug');
