disadvantages of this point, but here I want to say something practical: When you use node. when writing code in JS, you need to consider whether your task is slow or I/O-intensive. The asynchronous method is used to process callback or the event processor is used to process slow tasks.Most importantly, you must ensure that the Code does not allow a request to occupy too long events on the node's main thre

("./circle.js");//require通过引入模块文件，找到exports对象提供的接口console.log("The area of a circle of radius 4 is " + circle.area(4));Writing a slightly larger program typically blocks the code. In NodeJS , the code is generally reasonably split into different JS files, each file is a module, and the file path is the module name.When writing each module, there are require、exports、module three pre-defined variables available for use.The module name can use a relative

you're getting deeper into your programming, you'll find that you don't have to be proficient in every tool, API, and framework you use. Use the knife on the blade, not the hammer as a drill. Learn about the scenarios and issues that each tool applies to, and then find the most appropriate scenario for the tool. If you want to become a superhuman generalist (programmers often want to know everything), you
