JavaScript 嵌入的接口

处理自己的异步资源执行 I/O、连接池或管理回调队列等任务的库开发者可以使用 AsyncResource JavaScript API 以便调用所有适当的回调。

Library developers that handle their own asynchronous resources performing tasks like I/O, connection pooling, or managing callback queues may use the AsyncResource JavaScript API so that all the appropriate callbacks are called.
