Node.js Chinese Reference Manual

For the "Node.js Chinese Reference Manual", simply put, Node.js is JavaScript running on the server side. Node.js is a platform built on the Chrome JavaScript runtime. Node.js is an event-driven I/O server-side JavaScript environment based on Google's V8 engine. The V8 engine executes Javascript very quickly and has very good performance.

Node.js is an open source, cross-platform JavaScript runtime environment that can run JavaScript on the server side.

Node.js is owned and maintained by the Node.js Foundation and has a partnership with the Linux Foundation.

Node.js uses the V8 running code developed by Google and uses technologies such as event-driven, non-blocking and asynchronous input and output models to improve performance and optimize the transmission volume and scale of applications. These techniques are typically used in data-intensive, real-time applications.

Most basic modules of Node.js are written in JavaScript language. Before the emergence of Node.js, JavaScript was usually used as a client-side programming language, and programs written in JavaScript often ran on the user's browser.

The emergence of Node.js enables JavaScript to be used for server-side programming.

Node.js contains a series of built-in modules that allow the program to run as an independent server without Apache HTTP Server or IIS.

Tip: Before continuing with this tutorial, you should know some basic computer programming terminology. If you have studied Javascript, PHP, Java and other programming languages, it will help you understand Node.js programming faster.

Node.js Advantages

As an emerging front-end framework and back-end language, Node has many attractive features:

• ##RESTful API

• Single-threaded

• Node can still process tasks concurrently without adding additional threads - Node. js is single threaded. It implements concurrent operations through the event loop, and we should make full use of this - avoid blocking operations as much as possible, and instead use non-blocking operations.

• Non-blocking IO

• V8 virtual machine

• Event driven
