What is Node.js?
Node.js is an open-source, cross-platform runtime environment built on Chrome's V8 JavaScript engine. It allows developers to execute JavaScript code server-side, enabling the creation of fast, scalable applications. Known for its non-blocking, event-driven architecture, Node.js is ideal for real-time applications like chat, API services, and microservices.
Its ability to handle multiple concurrent requests efficiently makes it popular for building high-performance, scalable web and mobile apps.
