The Nodejs platform utilizes an asynchronous event-driven I/O model that allows it to be one of the fastest web frameworks available.
It is able to handle more concurrent connections than other frameworks because of this. Applications built with Nodejs are more responsive and scalable, even on high-latency networks like mobile.

Introduction to NodeJs
Node.js is a JavaScript runtime environment that has been widely adopted by software developers for its ease of use with Node.js modules, libraries, and frameworks. This technology is based on V8 for many of the features needed to run the full-stack JavaScript.
Some of the things that make Node.js so fast are the Asynchronous I/O, small event loop, and non-blocking I/O nature with JavaScript language syntax for concurrency. This is an open-source project based on Google Chrome’s V8 JavaScript engine and has its own API and syntax. Node.js is written in JavaScript. It is most often used as a server-side web framework, but it can also be used in the browser.
Why is Nodejs is faster than other frameworks?
Nodejs is fast, thanks to the V8 JavaScript engine that powers Google Chrome. Node has many features that can be found in most run-time environments, but due to the fact that it’s implemented in Javascript, it runs blisteringly fast. Nodejs is a complete JavaScript solution intended to work as an alternative to the CGI, Java, PHP, or ASP.NET runtimes. It’s a platform built on the Google Chrome JavaScript runtime for server-side scripting.
Node has some nice features that make it a good fit for web development. Node is based on the ideas of Google’s server-side programming language, V8, which is a dialect of JavaScript. However, instead of compiling down to machine code, Node actually compiles down to Javascript. This means that, even while running, the underlying machine instructions are actually running Javascript. This is a huge boon for performance since it means that Nodejs is very quick to execute.
Node also allows for Ajax-style asynchronous requests, which makes the framework a very powerful tool for web development. Because Node is based on Javascript, it is also compatible with all the other Javascript-based programming languages.
Top 3 Factors That Make Nodejs Fast
1) Event Loop
One advantage of NodeJS is its event loop model. The event loop mimics how web browsers work by letting developers listen for and respond to asynchronous events as quickly as possible. NodeJS is the first JavaScript runtime to feature a single thread of execution that’s isolated from the rest of the process. This allows developers to write code that is both asynchronous and non-blocking.
2) Event-Driven
NodeJS is event-driven. This means that it is highly scalable and is not as resource intensive as other frameworks. It also means that your code is always running. It’s written in JavaScript, so it’s easy to improve and maintain. NodeJS is a full-stack framework. It gives you access to all of the server-side APIs that you’d expect from a full-blown framework such as ExpressJS.
3) Non Blocking
Node is non-blocking. This means that it doesn’t have to wait for the results of an operation to return before it can continue. Instead, it can continue with other work while waiting for the results. This is a very different approach than that of other servers such as Ruby on Rails or.NET. This makes it more suitable for things that are IO-bound, like file I/O.
Conclusion
Nodejs was created in 2009 to address the need for a fast, scalable server-side scripting language. It has since grown into one of the most popular web development frameworks in the world. Big companies are now using Nodejs as well because of its fastness and popularity.
