NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Hermes 是一个经过优化的 JavaScript 引擎，可在 Android 端快速启动 React Native 应用程序。JavaScript 引擎（例如 V8）具有即时（JIT）编译器，可在运行时对代码进行分析以生成优化的指令。而 Hermes 采用了另一种方法，将 JavaScript 代码提前编译（AOT）为优化的字节码。这样做的结果是，你可以获得更小的 APK 图片大小，更少的内存消耗和更快的启动时间。我们正在一些 React Native 应用中认真评估 Hermes，建议你也这样做。
