Advantages of using Node JS for your web application

In today's competitive and digital market, having a stunning presence on the internet has become essential. A robust and modern online presence is what businesses need to stay ahead and for this, they need to adopt effective and advanced tech stacks. One such popular technology used for web development is JavaScript. JavaScript is one of the most widely used client-side development programming languages that supports a wide range of frameworks, libraries, and integrated development environments or IDEs out of which some popular ones are Node Js, AngularJS, and React JS just to name a few. Here, in this article, you can find out the advantages of using Node JS development for your web project.

Before looking at the advantages, let's have a clear idea of what Node JS is. 

Node JS is one of the most popular runtime environments that's based on the V8 JavaScript code of Chrome. It was introduced back in the year 2019 by Ryan Dahl. Node JS is an open-source framework that allows web developers to develop real-time web solutions. Because of its non-blocking asynchronous structure and its features, Node JS has become one of the most favoured choices for web development in a couple of years. Business giants like Walmart, Netflix, Uber, eBay, and many more are using this JavaScript framework for their web applications. 

Now, let's dive into the advantages of using Node JS. 

Node JS is continuously gaining popularity in web development because of its features and capabilities. It is the best bet for building real-time web application development and handling huge amounts of data. Here are the advantages discussed in detail. 

Scalable web application development:

Node JS offers high scalability. The framework enables multiple nodes to simultaneously run and interact with each other and this is an advantage over the other back-end web development tools or frameworks. Node JS has the cluster module which is responsible for things like load balancing for all CPU-intensive tasks. This is one of the biggest advantages of Node JS. You can run multiple nodes at one go and the cross-platform web development runtime environment will balance the workload automatically. 

The framework allows dividing the web application into smaller instances and horizontal partitioning of the web apps. You can show different versions of the application to the users based on the user interest, location, age, language, etc. This enhances personalisation and reduces the workload. Node JS child processes interact with each other and operate quickly for sharing the same origin. 

High performance:

Node JS is known for offering enhanced performance and facilitating easy and efficient processing of large amounts of data at the same time. This is a perfect option for back-end web development. Node JS interprets JavaScript codes using the V8 JavaScript engine of Google. The web app development engine of Node JS helps in compiling the codes directly into machine codes, making it easy to write the server-side codes and implement them. 

The server-side Node JS technology ensures accelerated code execution and the runtime environment of Node JS supports non-blocking operations. Node JS, as the single-threaded event loop, uses multiple working threads for executing the asynchronous codes and is non-blocking which means that the call-back function will be delegated to that event loop but will be executed by different threads. 

Powerful data processing:

Node JS is a server-side web development scripting language and can be considered as the runtime environment that facilitates the easy processing of thousands of requests at the same time. This is an ideal tool for efficient data handling. Node JS adopts the asynchronous architecture for the upcoming requests to process them together along with the first one. 

Control-flow features:

Node JS is a favoured back-end web development platform again because of its asynchronous structure. Whenever a function is executed, the code automatically sends a callback. And as the number of functions keeps increasing, the number of callbacks also increases and is known as the callback hell. 

The control flow feature of this framework gives a way out. Node JS helps to map the functions and sort them out through callbacks. It automatically integrates similar functions and finds the necessary features in a folder or by search. 

V8 Engine:

V8 engines are the best engines that were initially introduced for Chrome but now the Node JS development team has readapted the v& engine to the JavaScript runtime environment purpose. It’s written in the C++ language for compiling the functions when written in JavaScript language into Machine code for enhanced speed and performance. V8 engine demonstrates speed and performance improvements every year and offers tons of benefits. 

Node JS is the browser-specific JS runtime environment that is built on the V8 JavaScript engine of Chrome, which uses a call-back function for handling the HTTP requests, with a non-blocking I/O model for achieving efficiency while staying lightweight. 

Concurrent request handling:

Node JS enables the handling of multiple concurrent requests simultaneously at the same time. This is one of the most significant advantages of using Node JS. 

Lesser loading time:

Node JS has a caching module that helps to reduce the overall loading time. Programmers can execute the codes in a hassle-free way. Besides, having this caching module helps the websites or web applications easily get a request and transfer it to the in-app memory. This feature enables users to get results on the web pages in just a fraction of a second. 

All these advantages of Node JS contribute towards making it a favourable choice for web application development.
