This article mainly introduces the meaning of node.js, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand.

Node.js is a JavaScript running environment based on Chrome V8 engine and a development platform for JavaScript to run on the server side. What Node can do: 1, develop websites with complex logic; 2, develop large-scale Web applications based on social networks; 3, develop command-line tools, and so on.

This tutorial operating environment: windows7 system, nodejs version 12.19.0, DELL G3 computer.

Node.js is a JavaScript running environment based on Chrome V8 engine. It uses an event-driven, non-blocking IPUP O model, which makes JavaScript run on the server-side development platform. It makes JavaScript become a scripting language on a par with PHP, Python, Perl, Ruby and other server-side languages.

Before Node.js, JavaScript could only be run in a browser, used as a web script, add special effects to a web page, or communicate with the server. With Node.js, JavaScript can break away from the browser and use it directly on the computer like other programming languages. It can do whatever it wants and is no longer restricted by the browser.

What can node.js do?

Node.js can do much more than just develop a website. With Node.js, you can easily develop:

A website with complex logic

Large-scale Web Application based on Social Network

Web Socket server

TCP/UDP socket application

Command line tool

Interactive terminal program

Native applications with graphical user interface

Unit testing tool

Client-side JavaScript compiler.

Node.js has built-in HTTP server support, which means you can easily implement a combination of a website and a server. This is different from PHP and Perl, because when using PHP, you must first build a HTTP server such as Apache, and then use the module load or CGI call of the HTTP server to present the execution results of the PHP script to the user.

When you use Node.js, you don't have to build an extra HTTP server, because Node.js itself has one built in. This server can not only be used to debug code, but also can be deployed to the production environment itself, and its performance is sufficient to meet the requirements.

Node.js can also be deployed to non-web applications, such as a command line tool. Node.js can also call the code of CActuary +, which can make full use of many existing function libraries, and can also implement the parts that require very high performance.

Thank you for reading this article carefully. I hope the article "what is the meaning of node.js" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel, and more related knowledge is waiting for you to learn!
