This is our low-level asynchronous function. We can use generators to establish a communication channel and write asynchronous code in a synchronous programming style. run(function* () { console.log("Starting") var file = yield readFile("./async.js") // [1] console.log(file.toStri

more importantly, it depends on the open source Library at the upper layer. Express + (mongo + mongoose) | (node-mysql + sequencee) CRUD development is also fast, more importantly, Node's asynchronous database I/O performance is much higher than that of Python. Some people say that Node lacks a "mature" Big framework. In fact, this is related to the development

traditional Apache/PHP instances. However, Node runs quickly and efficiently. How is this done? Share the execution time and place intensive IP address processing in other threads for processing. I can write a long article to discuss the advantages and disadvantages of this point, but here I want to say something practical: When you use Node. when writing code in js
