Answer» Here is the list of important features of Node.JS - No buffering: Node.js applications never buffer any data(ASCII). These applications simply output data in chunks.
- Extremely Fast: Node.js is built on Google Chrome’s Javascript V8 Engine so its library is very fast in code execution. As you are aware Javascript is used to built CLIENT side applications which is also built on V8 engine, so this makes Node JS applications faster.
- I/O is Asynchronous and Event DRIVEN: All APIs of Node.js library are asynchronous i.e. non-blocking. So a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification MECHANISM of Events of Node.js helps the server to get a response from the previous API call. It is also a reason that makes it is very fast
- Highly Scalable: Node.js is highly scalable because event mechanism helps the server to respond in a non-blocking way.
