Node.js vs. Python for backend Python stands out for its capacity to handle machine learning and numerical computations in the field of back-end development. Choosing the right programming language and framework package depends on the specific needs of your application. Node.js is particularly benef...
The researchers state that using Node.js for backend and other tasks is able to enhance their applications’ performance. This claim has become so popular in the IT-sphere that many programmers decided to change their codes’ languages to Node.js. This may be caused by the fact that many gi...
我们知道,nodejs实现异步机制的核心便是libuv,libuv承担着nodejs与文件、网络等异步任务的沟通桥梁,下面这张图让我们对libuv有个大概的印象: 这是libuv官网的一张图,很明显,nodejs的网络I/O、文件I/O、DNS操作、还有一些用户代码都是在 libuv 工作的。 既然谈到了异步,那么我们首先归纳下nodejs里的异步事件: 非...

Nodejs 为单线程的,在单线程模式下,任务都是顺序执行的,但是前面的任务如果用时过长,那么势必会影响到后续任务的进行,通常 I/O 与 cpu 之间的计算是可以并行进行的,但是同步的模式下,I/O的进行会导致后续任务的等待,这样阻塞了任务的执行,也造成了资源不能很好的利用。

Event Loop is a programming construct that waits for and dispatches events or messages in a program. 1、每个Node.js进程只有一个主线程在执行程序代码,形成一个执行栈(execution context stack)。 2、主线程之外,还维护了一个"事件队列"(Event queue)。当用户的网络请求或者其它的异步操作到来时,node都会...
