1. High Performance: Node.js interprets JavaScript code via Google's V8 JavaScript engine which compiles the JavaScript directly into machine code making it faster.

2. Single Threaded but Highly Scalable: Node.js uses a single threaded model with event looping. This event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests.

3. No Buffering: Node.js applications never buffer any data. These applications simply output the data in chunks.

4. Asynchronous and Event Driven: All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data.

5. Open Source: Node.js has an open source community which has produced many excellent modules to add additional capabilities to Node.js applications.

6. Good for Real-Time Applications: Node.js is a good fit for real-time applications: online games, collaboration tools, chat rooms, or anything where you need to see updates immediately.

7. JSON Support: Node.js has built in support for JSON which allows you to build APIs quickly and easily.

8. Unified Database Queries: Node.js can be used to write database queries for databases like MySQL, MongoDB, CouchDB and others which support JavaScript natively.

9. Easy to Learn: Since JavaScript is a popular language most front-end developers are comfortable with it. Therefore, development in Node.js becomes easier for a developer who knows JavaScript.

10. High Productivity: Node.js uses JavaScript for both the client and server side, this makes it easier to send data between the server and the client for real-time changes. This increases the productivity of developers.
