JavaScript 嵌入器 API

【JavaScript embedder API】

处理自身异步资源（如执行 I/O、连接池管理或管理回调队列）的库开发者可以使用 AsyncResource JavaScript API，以确保所有适当的回调都被调用。

【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.】
