CTOnews.com, November 16, Node.js is an open source, cross-platform JavaScript environment that can run JavaScript on the server. The latest version is based on the V8 JavaScript 11.8 engine developed by Google, which allows developers to write server-side and browser-side programs in JavaScript at the same time, in order to create a more convenient development process.

Node.js 21.2.0 has been officially released, which is a small fix for Node.js 21. Friends can click here to visit the project address.

According to officials, one of the biggest highlights of Node.js 21 includes a built-in WebSocket client that connects directly to the WebSocket server through a program with Node.js without having to rely on a third-party kit library.

In Node.js 21, developers only need to use "node-experimental-websocket" to use the WebSocket function, which allows real-time two-way traffic between the server and the client, which is very useful for IM chat functions, real-time updated websites and interactive games.

The main changes in Node.js 21.2.0 version attached to CTOnews.com are as follows:
