Inside of Node.js

Node.js use non-blocking, event-driven I/O to remain lightweight and efficient in the face of data-intensive real-time applications that run across distributed devices.

Node.js use Chrome’s V8 JavaScript engine.

NodeJS being light weight and efficient. Because uses an asynchronous event-driven I/O model, ensuring that almost no function in Node directly performs I/O.

What is NPM?

npm is the package manager for the Node JavaScript platform. It installs modules so that node can discover them and intelligently resolves dependency issues. It may be configured to support a wide range of scenarios. It’s most widely used for publishing, discovering, installing, and developing node programs.
