What makes it special? It is free. It runs on various platforms (Windows, Linux, Unix, Mac OS X, and more!) And it runs on asynchronous programming.
And what does that imply?
You run a retail shop. Multiple people come to your shop, ask for an item, you pick it up from the storage cabinet, and give it to the customer. And till then, the other customers are waiting for their turn in a queue. Time-consuming, isn’t it?
Well, that is how most servers worked before Node.Js. Now when there is a file request, Node.Js sends the request to the computer system and then takes the next request, returning the files when found. Saving time, memory, resources, and the building block to efficient servers – that is Node.Js for you.
Is it a fail-proof option? Will hiring a Node.Js developer be really effective? Well, the business leaders are using it – there must be something about it, right?

Advantages of Node.Js in a Nutshell
Every platform that uses Node.Js framework uses it for a different advantage that it offers. And here is a list of those advantages:
2. Non Blocking
3. Data Streaming
4. Real Time
5. Unified Database
6. Easy Coding
7. Quick Development
8. Apt for Androids
10. Performance Enhancement
Performance Metrics That Can be Used
Now, coming to the real tests. What metrics should be used to test the efficiency or otherwise of Node.Js? What can help you decide whether or not the hype about Node.Js is substantial? Is it just a white elephant or a lion that is all set to roar?
Let theses metrics guide you:
1. Event loop
What does it mean: The ability to execute code in a loop
Node.Js is famous for its no-block nature. The system can handle async operations and unlimited operations can be processed
2. Real-time User Behavior
What does it mean: This metrics is all about response time measurement
Node.Js helps several applications process multiple requests in a matter of seconds. In conclusion, efficiency is proven in this regard!
3. Process Memory
What does it mean: Manage application memory so as to prevent memory leaks
Node.Js’ extremely efficient support tool, Garbage collector comes to play here. You can check how much time it spends on the tool and check for building trends by comparing memory after each run to see the results for yourself.
4. External Frameworks
What does it mean: Dependence on other servers, systems, and database
You can check the request rate, response time, APIs, content size, and error rates for gathering reliable insights.
The Bottom Line
Node.Js is the present and future of web application development. But, as it is always said, a brilliant idea in the hands of a fool can wreak havoc. And so, you need an experienced, innovative, and quick-learning Node.Js developer who can match the capabilities of Node.Js and use it to build prolific scripts and a shining future for you!
