Best Node JS Training Course in Chennai

JavaScript’s rising popularity has brought with it a lot of changes, and the face of web development today is dramatically different. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine just several years ago, or were encapsulated within sandboxed environments like Flash or Java Applets.

Node.js is a packaged compilation of Google’s V8 JavaScript engine, the libuv platform abstraction layer, and a core library, which is itself primarily written in JavaScript.” Beyond that, it’s worth noting that Ryan Dahl, the creator of Node.js, was aiming to create real-time websites with push capability, “inspired by applications like Gmail”. In Node.js, he gave developers a tool for working in the non-blocking, event-driven I/O paradigm. After over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections.

Frequently Asked Questions

Node.js is Server-side scripting which is used to build scalable programs. It is a web application framework built on Google Chrome's JavaScript Engine. It runs within the Node.js runtime on Mac OS, Windows, and Linux with no changes. This runtime facilitates you to execute a JavaScript code on any machine outside a browser.

Yes. It is released under MIT license and is free to use.

  • Node.js is asynchronous and event-driven. All API?s of Node.js library are non-blocking, and its server doesn't wait for an API to return data. It moves to the next API after calling it, and a notification mechanism of Events of Node.js responds to the server from the previous API call.
  • Node.js is very fast because it builds on Google Chrome?s V8 JavaScript engine. Its library is very fast in code execution.
  • Node.js is single threaded but highly scalable.
  • Node.js provides a facility of no buffering. Its application never buffers any data. It outputs the data in chunks.

We can manage the packages in our Node.js project by using several package installers and their configuration file accordingly. Most of them use npm or yarn. The npm and yarn both provide almost all libraries of JavaScript with extended features of controlling environment-specific configurations. We can use package.json and package-lock.json to maintain versions of libs being installed in a project. So, there is no issue in porting that app to a different environment.

  • js makes development simple because of its non-blocking I/O and even-based model. This simplicity results in short response time and concurrent processing, unlike other frameworks where developers use thread management.
  • js runs on a chrome V8 engine which is written in C++. It enhances its performance highly with constant improvement.
  • With Node.js, we will use JavaScript in both the frontend and backend development that will be much faster.
  • js provides ample libraries so that we don't need to reinvent the wheel.

Node. js may not be the hottest career out there, but it's clear enough that it's not just a trend. If you're looking to learn a technology that provides a stable, high-paying job, Node. js would be an excellent choice.

Node js is faster than java because it uses an asynchronous event-driven I/O model and does not have the overhead of the Java runtime environment. Node js also has a large ecosystem of libraries and frameworks which makes it easier for developers to build web applications.
