Welcome to the beginners' tutorial on Node.js! If you are new to Node.js and want to learn more, this guide will help you get started.

简介

Node.js is an open-source, cross-platform JavaScript runtime environment that enables developers to execute JavaScript code outside of a browser. It's known for its non-blocking, event-driven architecture, making it efficient for building scalable and high-performance applications.

安装 Node.js

Before you start, you need to install Node.js on your system. You can download it from the official Node.js website.

基础概念

Here are some of the basic concepts you should be familiar with before diving into Node.js:

  • JavaScript: Node.js is built on JavaScript, so having a good understanding of the language is essential.
  • NPM: Node Package Manager (NPM) is a package manager for Node.js that allows you to install and manage packages.
  • Modules: In Node.js, you can write code in modules and import them into your application.
  • Asynchronous Programming: Node.js uses asynchronous programming to handle I/O operations, which makes it efficient and fast.

简单示例
