Business reasons for using NodeJS

Node.js is a software platform built on Google’s V8 JavaScript engine. It makes use of an event-driven, non-blocking I/O model and a single-threaded event loop which allows high throughput and application scalability.Here, are some of the benefits that Node.js provides.

1. Increases productivity of developers   

Node.js allows developers to write JavaScript on both the client side and the server side. That means developers can use similar modules on both server side and client side (Isomorphic programming). Node also improves the build times considerably. That’s a big win when it comes to developer productivity, maintenance, and time to market.   

2. High Performance

Node.js provides an event-driven architecture and a Non-blocking I/O API that optimizes an application's throughput and scalability.Non-blocking I/O model supports the execution of system to be continued without waiting for I/O operations to complete.The following image shows how performance stats improved when Paypal team used Node.js

You can see that the node.js application had:

• Double the requests per second vs. the Java application. This is even more interesting because initial performance results were using a single core for the node.js application compared to five cores in Java. They expect to increase this divide further.
• 35% decrease in the average response time for the same page. This resulted in the pages being served 200ms faster— something users will definitely notice.

3. Reduced Infrastructure cost

Higher performance because of Non-blocking nature of node has reduced infrastructure cost. Many popular enterprises like Paypal, Netflix, LinkedIn, GoDaddy, Uber have shifted to Node.js in there experiences Node has brought down the number of servers required to 1/4 of what were needed earlier.Much better performance and lower memory overhead than other tested options, running up to 20x faster in some scenarios.

4. Strong community support

Community support for NodeJS is exponentially increasing day by day today there are over 3 lakhs node modules which is highest than any another other language.Here are few stats and comparison with other popular languages :

5. Collaboration

With modular design and such a large ecosystem to work with, Node.js developers enjoy increased collaboration. Java’s tendency to create large monolithic systems and deep alliance with Object Oriented programming make sharing discrete functional components difficult. When code is shared in Java, it’s typically in the form of large libraries. Node.js makes building applications easier and faster with smaller, more focused components that teams company-wide can collaborate on together to produce. These components have specific functionality that’s more easily shared across teams and applications.

Universal JavaScript or Isomorphic JavaScript — is the practice of sharing JavaScript code across both frontend and backend Node.js code. This creates new ways to collaborate and allows for more efficient use of time and effort by teams.
