node. JS callback functionThe immediate manifestation of node. JS asynchronous programming is callbacks.Asynchronous programming relies on callbacks to implement, but it cannot be said that the program is asynchronous after using the callback.The callback function is called after the task is completed, and

This article mainly introduces Node. callback and code design patterns in js asynchronous programming. Although long string parentheses during callback writing are not very nice in most cases, Node's asynchronous performance is indeed good, for more information, see the event mechanism and asynchronous IO, the biggest selling point of NodeJS, which is not transpa
