 In OpenHarmony, you can use the N-APIs in C APIs to implement interaction between ArkTS/TS/JS and C/C++. The  N-API names are the same as those in the third-party **Node.js**. Currently, OpenHarmony supports some N-APIs. For details about the APIs supported, see [arkui_napi](https://gitee.com/openharmony/arkui_napi/blob/master/libnapi.ndk.json).
