What is Node.JS?
Unlike the current web response model, where communication is initiated solely by the client. Web Sockets are replaced by creative push technology in Node.js. As a result, the server and client will establish a two-way, real-time link and share useful data.
Node.js is much more socially and technically successful than its current competitors, such as PHP, Python, and ROR. Companies who use Node.js, whether industry giants like Microsoft, Walmart, PayPal, or comparatively younger companies like Groupon and Netflix, have overwhelmingly agreed on the benefits of using Node.js growth.
Let’s talk more about its popularity:
- It’s very Fast
As a result, reading and writing to the file system, network connections, and databases is very easy in Node. It enables programmers to create highly scalable network applications capable of handling large numbers of concurrent connections with high throughput.
- It is Commonly Used
- Multi-layered Language
Node.js typically employs a simple event-driven architecture. This means that all you do on it is a sequence of asynchronous callbacks, including every process and call. This allows Node to operate on a single thread, as opposed to other web technologies, which spawn a new thread for each client request. This not only makes it lightweight, but it also makes Node’s non-blocking I/O function possible.
- Can be Hosted Anywhere
Or, to put it another way, almost everywhere! After the explosive growth of Node.js usage in recent years, most cloud-based hosting providers and web servers now support Node.js web applications out of the box. Google, Amazon AWS, Heroku, Microsoft IIS, Microsoft Azure, and a slew of other companies are among them.
- High Performance
PayPal uses Node.js and claims to have doubled the number of requests per second thus cutting response time in half. Wal Mart, on the other hand, had a great experience with Node.js in 2013, when they used it to handle all of their mobile traffic on Black Friday, the busiest shopping day of the year. Amazingly, Wal Mart servers did not exceed 1% CPU usage on Black Friday, despite having 200,000,000 users online. To manage mobile traffic, LinkedIn switched from Ruby to Node and the the number of servers from 30 to 3, a nearly 90% reduction. The new system was up to 20 times faster than the previous one. All of these statistics show that Node.js is capable of high efficiency.
- Easy to Maintain
When new specifications are fed, traditionally designed applications become less adaptable and rigid. They eventually begin to squeak under the strain for which they were not designed. Developing new services with Node.js, on the other hand, is a lot simpler. Instead of a single big application, Node lets you create a bunch of small ones. This makes it much easier to make improvements or incorporate new features without having to go deep into the code base.
Yes, Node.js is really common right now. It has a wealth of features that developers can use to build highly reliable and scalable web applications. But it’s worth a shot until it’s too late. After all, this is the web development environment!
