Runoob

Site Introduction

Runoob Tutorial is a free online programming learning platform for Chinese-speaking users. From your first line of HTML to AI Agents, tutorials, examples, and quizzes can all be found here.

No registration required, no payment required—just open it and start learning. Since its launch in 2013, many programmers' first "online textbook" began right here.

Core Features

1. Full-Stack Technical Tutorials
Covers 13 major categories and more than 50 technical fields: Python, JavaScript, Java, Go, Vue, React, MySQL, Docker, Git, as well as AI Agent, Ollama, LangChain, and other intelligent development content. Every tutorial starts from Hello World, with code examples, so even complete beginners can follow along.

2. Online Code Examples
HTML, CSS, JavaScript, Ajax, jQuery, XML, Java, and other languages all have runnable online examples. Read and modify at the same time, and see the results immediately after making changes—much more intuitive than just reading documentation.

3. Reference Manuals and Quizzes
Each language has an independent reference manual for convenient syntax lookup. It also provides online quizzes for HTML, CSS, JavaScript, Python, Java, SQL, Git, and more, so you can test yourself after learning and identify gaps.

4. Practical Tools and Learning Aids
Built-in Runoob Tools include JSON formatting, an HTML color picker, PNG/JPEG compression, JS obfuscation, and more. There are also Runoob Notes, local bookmarks, and a Programmer Learning Path to help you build your own learning route within the site.

Unique Advantages

1. Extremely broad Chinese coverage, from frontend to backend, databases to AI—you can find almost everything on one site without switching platforms
2. Complete trio of tutorials + examples + quizzes, providing a full self-learning path, especially suitable for zero-based beginners
3. Continuously updated hot topics, keeping up quickly with new subjects such as Ollama, Claude Code, Vibe Coding, and Next.js

Practical Highlights

• Every tutorial has a consistent structure, allowing you to check syntax, run examples, and take quizzes all on the same site
• There is a "Programmer Learning Path" for when you don't know where to start—just follow the route

Objective Limitations

1. Some content is compiled from external sources such as MDN and W3Schools, so individual chapters may be outdated or not deep enough; complex projects still require the official documentation
2. The pages contain advertisements, so the reading experience is not as clean as purely non-profit sites; there are also no interactive services such as video courses or live Q&A

Frequently Asked Questions

1. Is Runoob Tutorial really free?
Yes. Tutorials, examples, manuals, quizzes, and tools are all free, and there is no membership system. The official team also does not charge for an app—if you see a paid "Runoob Tutorial App," it is counterfeit. Do not buy it.

2. Can complete beginners learn from it?
Yes. The official positioning is "zero-barrier entry." From Hello World to practical examples, just read chapter by chapter. It is recommended to first choose one direction (such as frontend HTML/CSS/JS, or Python) rather than trying to learn everything at once.

3. What is the difference between its content and W3School?
The structure is similar: both are "tutorials + examples + reference manuals." Runoob Tutorial has broader coverage, especially in areas such as AI, DevOps, and mobile development that W3School hardly touches. In terms of depth, both lean toward beginner level; for advanced learning, you still need the official documentation.

4. Is the tutorial content accurate?
The official disclaimer states clearly: it does not guarantee that the content is completely correct, and some material is compiled from MDN, Wikipedia, official documentation of various languages, and other sources. It is sufficient for learning the basics, but for production environments or in-depth interview questions, cross-verification is recommended.

5. Is there an app?
There is an Android beta APK. iOS users can add the official website to the home screen and use it like an app. Note: the official team has not released a formal version on the App Store or app marketplaces. Paid apps are all fake.

6. How can I find the technology I want to learn as quickly as possible?
Browse by major category on the homepage (Python, frontend, AI, etc.), or use the search box at the top to search keywords directly. You can also check the "Programmer Learning Path" and follow it step by step.

7. What quiz score counts as passing?
Quizzes are mainly self-assessment tools and do not have an official "passing line." It is recommended to review the corresponding chapters for any wrong answers. Once you can consistently answer more than 80% correctly, move on to new content for more solid results.
