Pros and cons of Node.js

Advantages:
1. Asynchronous event-driven;
2. Non-blocking I / O;
3. Single-threaded;
4. Outstanding performance of V8 engine;
5. Based on Javascript, low barrier to popularization
Disadvantages
1. Not suitable for computationally intensive applications;
2. Not suitable for large memory applications (due to the V8 engine's memory design restrictions);
3. Not suitable for a large number of synchronous applications (at this time Nodejs asynchronous will cause trouble)
