Node.js

Node.js allows developers to create fast, event-driven applications using JavaScript outside the web browser. Ideal for building APIs, web servers, microservices, and real-time solutions, Node.js uses a non-blocking, asynchronous I/O model that handles multiple requests concurrently. Its active open-source ecosystem includes npm (Node Package Manager), which offers thousands of reusable modules. Node.js is widely adopted for cloud applications, RESTful APIs, and Internet of Things (IoT) solutions. This runtime environment helps developers leverage their JavaScript skills to deliver server-side logic, simplify development workflows, and increase application speed. Node.js is well-suited for startups to enterprise-level projects requiring scalability and efficiency.
