Description

Section titled “Description”

Node.js is a popular open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. It is commonly used for building scalable network applications and is known for its event-driven, non-blocking I/O model. Node.js is widely used for server-side scripting and has a large ecosystem of libraries and frameworks.
