一、下载
去nodejs下载node.msi安装文件包,里面包含了node.js和npm;
双击node.msi就行了,选择安装路径和npm;
二、设置环境变量
[新版本都不需要设计环境变量了,软件会自动写入环境变量]
计算机(或者我的电脑)右击属性-》高级系统设置-》环境变量。
新建一个用户变量。
变量名:NODE_PATH
值:C:\Program Files\nodejs\node_modules
注意:值为nodejs安装目录
1. cd D:\20171016 //项目文件目录(包含项目文件名) 2. d: 3. npm start 4. 在浏览器中输入http://localhost:10999
三、测试
1、写测试代码test.js
随便找个项目文件夹,再里面新建一个service文件夹,我的目录是E:\nodetest\service
注意:此路径不能有中文
再在里面新建一个UTF-8编码的js文件、文件名字随便起、我的文件叫test.js
在js文件里面增加入下代码
var http=require('http'); http.createServer(function (request,response){ response.writeHead(200,{'Content-Type':'text/plain'}) response.end("hello,world\n"); }).listen(8887); console.log('Server runing at http://127.0.0.1:8887');
2、运行
启动nodejs服务,window键+R,输入cmd然后回车
在命令行窗口中输入node E:\nodetest\service\test.js
注意:结尾不用加分号;
成功
在浏览器中输入http://127.0.0.1:8887/结果如下。

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
