Node.js is an open-source JavaScript runtime environment that allows developers to execute JavaScript code for server-side scripting and scalable network applications.
I have been working with Javascript for more than a decade and for the first few years I did not know what event loop was. It was not until I started working heavily with NodeJS when I realised there is something called event loop and what it does. Javascript queues up the code (funct...
通过把参数module传递给load()函数,hello.js就顺利地把一个变量传递给了Node执行环境,Node会把module变量保存到某个地方。 由于Node保存了所有导入的module,当我们用require()获取module时,Node找到对应的module,把这个module的exports变量返回,这样,另一个模块就顺利拿到了模块的输出: Copy vargreet =require('./hell...
Event-loop is one of the most important features of NodeJs framework which also explains how exactly the code gets executed in the Node environment. Event Loop comes with the stack, some web APIs, and a callback queue. Event-loop can be considered as an endlessly running single-threaded loo...
Event Loop: The Event Loop is the core of Node.js and it’s a genius idea. But, Don’t use Node.js for blocking, CPU-intensive tasks. Node.js is not suited for stuff like that. Node.js is suited for I/O stuff (like web servers). TL;DR Don’t use Node.js for CPU-intensive...

And in the case of most popular frameworks, Node.js takes the first place. What is Node.js used for? Node.js is basically used for non-blocking, event-driven servers because of its single-threaded behaviour. It is particularly used for traditional websites and back-end application ...
