Node.js

Node.js is a fast, open-source, server-side JavaScript runtime environment built on Chrome’s V8 engine. It allows developers to execute JavaScript outside the browser, making it ideal for building scalable backend services, APIs, real-time applications, and microservices with high performance and efficiency.

• Event-driven, non-blocking I/O architecture for high performance.
• Lightweight and highly scalable for modern backend systems.
• Supports building RESTful APIs and web servers.
• Large ecosystem via npm (Node Package Manager).
• Cross-platform support (Windows, Linux, macOS).
• Ideal for real-time applications like chat and streaming apps.
• Works seamlessly with databases like MongoDB, MySQL, and PostgreSQL.
• Strong community support and frequent updates.
• Easy integration with frontend frameworks (React, Angular, Vue).
• Supports microservices and cloud-native architectures.

To verify Node,js version, run : 
$node -v
$npm -v

Disclaimer: Node.js is a runtime environment and not a framework. Proper project structure, security practices, and dependency management are required for production-grade applications.
