Node.js is renowned for its high performance and scalability, qualities that draw businesses to hire Node.js developers. Much of this performance can be attributed to the platform’s non-blocking, asynchronous nature. However, truly mastering asynchronous programming in Node.js, a fundamental skill ...
NodeJs让很多前端开发者利用JS开发服务器变得异常的简单,而异步式I/O则是NodeJs的一大特点。 异步式:异步式IO又称非阻塞式I/O,异步式与同步式不同的是,当线程进行IO操作时,操作系统并不是暂停当前的线程操作,而是执行完I/O指令后,操作系统继续让当前线程执行下一条指令,当I/O操作完成后,会通过事件(event)通...

Control flow in Node.js is the sort of library for which almost all the developers have created and publish their own libraries. They usually aim at reducing spaghetti codes made of deep callbacks. I…
Node is non-blocking which means it can take many requests at once. In Node programming model almost everything is done asynchronously but many of the functions in Node.js core have both synchronous and asynchronous versions. Under most situation, we should use the asynchronous functions to get...
