Today we will introduce node's event loop mechanism, which is a basic concept of some interactive systems and part of the core of JavaScript language. For users who use browsers, JavaScript processes users' requests by handling click, mouse, and other related events. For a server like node, the event

Process is also an example of emitter. Can be used directly in the program.//Listening 1Process.on ("AA",function(data,state) {Console.log (' Monitor 1 '); Console.log (Data+ ': ' +State );});//Event 1Process.emit ("AA", ' Launch ', ' Event 1 ');//Listening 2Process.on ("AA",function(data,state) {Console.log (' Monitor 2 '); Console.log (Data+ ': ' +State );});//Launch 2Process.emit ("AA", ' Launch ', '

This article mainly introduces several important knowledge points of node. js: The Role of node. js, callback, synchronous and asynchronous code, event loop 1, and the role of node.

This article mainly introduces Node. in js, the event transmitter mode is used to implement event binding. This article also explains the basic knowledge of callback mode, transmitter mode, and event type. For more information, see Node
