Syllabus- Important Facts On Node.js
Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It was developed by Ryan Dahl in 2009, and it uses the V8 JavaScript engine, the same engine that powers Google Chrome. Node.js is widely used for building scalable, server-side and networking applications due to its non-blocking, event-driven architecture.
