Node.js: every back-end developer’s favorite

0

Node.js is currently the talk of the town, gaining popularity and momentum with developers everywhere. If you are wondering what is Node.js, it is an advanced server technology which allows users to not only build, but also run web applications by using JavaScript as its main language.

LinkedIn, PayPal and even eBay are some of the leading enterprises which are using Node.js for development. Why? Because Node comes with countless benefits which make it a suitable for back-end development. Statistics provided by W3Techs show a steady growth of Node.js this year, making it one of the most stable technologies.

Is there any difference between Node.js and JavaScript?

In terms of language, there is no difference between both. We can safely conclude that the JavaScript and Node.js used in browsers are pretty much the same. But what sets them apart if the unique difference between the set of APIs.

Now, in many you will find a variety of DOM/Web APIs which can improve interaction between UI and enable access to hardware, but only to a defined limit. Node.js on the other hand, comes with many APIs that make it the perfect match for back-end development including file system support, http requests, child processes and streams.

Is using Node.js worth it?

The answer to this question is a big yes. By using Node.js as your main server technology, the language remains the same for both the front end and back end. This significantly boost efficiency and cross-functionality of teams. Teamwork is the key to success. Node.js ensures everyone is on the same page and allows the code to be reused and shared.

However, the leading reasons why Node.js is so popular among back-end developers have been listed below:

Usage of JavaScript

JavaScript is without a doubt the language of most, if not all, developers across the globe. And it is one of the top languages used for the development of web application. Node.js uses JavaScript as the main language, allowing developers specializing in JavaScript to transition to Node.js easily.

Efficiently lightweight

Node.js runs on a single thread for every execution. This basic architecture makes it very lightweight as compared to other web development technologies which create a new thread for every single client request. This unique feature of Node.js builds the foundation for its non-blocking I/O platform.

Faster than most

Node.js is powered by V8, which can execute at lightning speed. The JavaScript is compiled into a native machine code making it more compatible. But moreover, the single thread event loop performing entire I/O operations sends asynchronous tasks and callback action, continuing with the rest of program and sync operation. The result of this is, faster network connections, reading/writing to file systems, operational executions and management of bulk data amounts.

Superior performance

Did you know that PayPal uses Node.js? This multimillion dollar company has stated that with Node.js, not only have they reduced the response time by 35%, but also significantly improved the number of requests per-second. Numerous other corporations such as LinkedIn and Walmart have applauded the high-performance capacity of Node.js over the years.

Easy modification and hosting

There are countless could-based hosting providers that use Node.js including Google, Microsoft Azure and Amazon. The rising popularity of Node.JS has increased its usage and acceptability of diverse hosting platforms. Alongside its hosting capacity, Node.js is far more flexible than other applications and can be modified with time to meet new requirements.

Node.js is becoming a basic language for developers everywhere. Businesses are keen on using this unique technology as it drives more robust growth and can be flexible for technological evolution in the coming years.
