Node.js, a backend JavaScript runtime built on Chrome’s V8 engine, has become an essential technology for developing scalable, efficient, and cross-platform applications. As an open-source and cost-effective solution, it has garnered popularity worldwide among developers who appreciate its high performance and non-blocking features. The Node JS Training in Chennai offers a comprehensive curriculum designed to provide in-depth technical knowledge and hands-on experience in dynamic web application development using Node.js.
Core Features of Node.js
Non-Blocking Architecture
The non-blocking feature is a major advantage of Node.js. Developers can execute tasks without waiting for previous tasks to complete, enhancing efficiency. This feature is particularly usefuls for web applications handling multiple requests simultaneously, as it allows other functions to continue processing without delay, leading to faster overall performance.

Single-Threaded with Asynchronous Processing
Although Node.js operates on a single thread, it uses multiple threads in the backend to handle asynchronous code. Node’s event loop and non-blocking I/O operations enable this, making it highly effective for applications that require handling numerous connections without slowing down, such as chat applications and gaming platforms.
Event-Driven Nature
Node.js relies on an event-driven architecture, where each API operates without blocking the server. This means that tasks are queued and processed as responses come in, allowing for seamless operation without lag, even under heavy workloads.

Node Package Manager (NPM)
Node’s package manager, NPM, is the world’s largest software registry, with over 690,000 code packages. It provides access to reusable code libraries and allows developers to easily manage dependencies. NPM also facilitates faster application development by providing ready-to-use components and modules, and many companies use it for private development, which enhances both productivity and code maintenance.

No Buffering
Node.js ensures data is not buffered but outputted in chunks, which improves the speed and user experience of applications, especially when streaming video or audio content. This characteristic makes it ideal for applications where uninterrupted data flow is critical.
Scalability and Lightweight Nature
Node.js’s lightweight technology makes it an excellent choice for microservices architecture, allowing developers to scale applications quickly and efficiently. This scalability, combined with a low memory footprint, enables developers to handle large amounts of traffic without compromising performance.
