Node js

Node.js is an open-source JavaScript runtime environment that allows developers to run JavaScript on servers. Released in 2009, Node.js utilizes an event-driven, non-blocking I/O model for high performance and scalability.

Node.js comes bundled with essential modules like HTTP, DNS, FS etc. This allows you to perform file operations, network communications, and more using JavaScript. The benefit is you can use one language – JavaScript across frontend and backend.

No, Node.js is not a framework itself. It provides the runtime environment on top of which frameworks are built. Express, Sails, Meteor etc are examples of popular frameworks written for Node.js.
These frameworks provide structure, patterns and helpful functionality so developers can focus on the app logic instead of rebuilding core components.

There are mainly 3 types of Nodejs frameworks available:
MVC Frameworks
MVC frameworks like Express implement the model-view-controller pattern to organize code into modular components for maintainability.
Full-stack Frameworks
Full-stack Nodejs frameworks like Meteor provide features to build complete apps covering both client and server side.
REST API Frameworks
Frameworks like Restify and LoopBack optimise for quickly developing REST APIs.

Here are some common use cases for Nodejs frameworks:

• Simpler routing for web servers instead of using Node.js bare modules
• Reduce boilerplate code through useful abstractions
• Built-in security against attacks like XSS, CSRF etc
• Faster development with features like templating, ORM etc
• An ecosystem of open source libraries for added functionality
• Following best practices and design patterns
