Node.js is server technology with which a variety of web applications can be created and run. It is very like Spring, Ruby-On-Rails, and the ASP.NET frameworks in what it can do. By leveraging the language of JavaScript it allows the various plugins and NPM-Node Package Manager to learn node JS work on its built-in lightweight web-server. Node.js is a web application that replaces web-sockets with push revolutionary technology.
This scores over the others because it offers a technologically latest web-app with real-time bi-way connections between the client and the server to exchange valuable data. The conventional web response is where the client initiates communication.
Node.js allows the application customization to be needs-based and has many features that make it extremely popular among developers. It is scalable, robust, state-of-the-art and fast. Node.js is the popular framework choice of developers today. It is definitely worth your time to learn node JS.
Here’s why.
Top Reasons for Node.js’s Popularity
1. JavaScript is popular:
Node.js uses JavaScript to build web applications. And, JavaScript is popular and perhaps the only front-end choice in browser web application building! It has been re-versioned many times over and has with Node.js revolutionized server language.
Since most developers are familiar with Java Script’s use transitioning to Node.js is an easy choice for most developers.
2. Speed:
Node.js running on JavaScript has V8 runtime used by Chrome and developed by Google to speed runtime in it. It can execute and compile super fast since it turns JavaScript into native code. It also has its O/I operations executed in an asynchronous manner on a single thread performing all popularly known as the magical event loop.
An application in Node.js when performing O/I operations it sends callback action and asynchronous tasks to the event loop while performing the rest of the program.
Once sync operations are complete automatically the event loop returns to the execute callback task. Unlike conventional looping needing both memory space and being hard to execute the event loop in Node.js is lightweight and executes at lightning speed making network connections and writing/reading to file system database easy.
Node permits scalable applications handling huge amounts of simultaneous connections on the network with high throughput.
3. Lightweight:
Node.js uses event-driven architecture meaning all tasks executed on it is a series of asynchronous callbacks. Thus a single thread is used without every client request generating a new thread. This makes Node.js lightweight and is the basis of Node’s I/O non-blocking feature. It is just as easy in the learn node JS feature!
4. Single layer language:
Node.js is a reusable language and unlike ASP.NET or Spring does not need another language to write server-side code. In C#, Java,VB.NET etc there are two languages namely the server-side and client-side. Node needs JavaScript only making the job of the developers simpler and easier.
5. Excellent performance:
Node.js is used by PayPal who reported a 35 per cent reduction of response time and doubling the number of requests/second.
WalMart, in 2013 deployed Node.js to handle mobile-based traffic on Black Friday, the busiest annual shopping time.
Yet, WalMart servers reflected 1 per cent CPU utilization with 200,000,000 users online. LinkedIn, moved to Node from Ruby to handle their mobile traffic. They reduced their server numbers to 3 from 30 a 90 per cent capacity reduction. The LinkedIn system speeded up 20x. That’s how Node.js performs!
6. Easy to host:
There are several web servers and cloud-based hosting providers supporting apps on Node out-of-the-box. Some of them are Heroku, Google, Microsoft-IIS, Amazon-AWS, Microsoft-Azure etc.
7. Maintain and modify easily:
Traditionally when requirements are fed the apps become rigid and less adaptive over time. But those applications on Node.js are in a bunch form of small applications. Thus adding new functionalities or making changes is easy and does not have to involve the code-base.
Conclusion:
Keeping in mind that the front-end developers are highly paid and never have to search for jobs Node.js is definitely the way to go in stack expansion. Node.js brings awesome benefits to developers in web application development and its popularity shows it is here to stay.
One must change with technology when technology changes rapidly as it does in current times. Do learn node JS at Imarticus Learning where technical skills and soft-skills are honed to make you career ready from day one.
