Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment based on Chrome’s V8 engine that enables developers to run JavaScript on the server-side. Node.js is primarily used to create fast, scalable, and high-performance server-side applications.

Node.js is based on an event-driven, non-blocking I/O model. This feature makes Node.js suitable for handling a large number of concurrent connections. Node.js is mainly used to create APIs, real-time applications, and microservices architecture-based applications.

Using Node.js and the help of npm (Node Package Manager), developers have access to a vast number of libraries and tools that make it easier to speed up the development process. Node.js is being used by many startups and large organizations due to its performance, scalability, and ability to create full-stack applications with JavaScript.
