Aynchronous and Event Driven - All APIs of Node.js library area unit aynchronous that's non-blocking. It basically means that a Node.js based mostly server not waits for a API to return information. Server moves to next API when calling it and a notification mechanism of Events of Node.js helps server to induce response from the previous API decision.

Very Fast - Node.js library is very fast in execution of code.

Single Threaded but highly Scalable - Node.js uses a single threaded model with event looping. Node.js uses a single threaded program and same program can services much larger number of requests than traditional server like open source.

No Buffering - Node.js applications never buffer any data. These applications simply output the data in faster.
