What is the NodeJS?

Node.js is an open-source and cross-platform JavaScript runtime environment. It is a popular tool for almost any kind of project.

Node.js is built on Google Chrome’s V8 JavaScript engine, its library is extremely fast for code execution.

Node Package Manager has more than 50,000 bundles, so whatever functionality is required for an application can be easily imported from NPM.

A Node.js app runs in a single process, without creating a new thread for every request.

Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm.

NodeJS Architecture

Node.js uses the “Single Threaded Event Loop” architecture to handle multiple concurrent clients.

Node.js is the epitome of exceptionally customizable and scalable tech.

The server engine utilizes an event-based, non-blocking I/O model. This makes the adaptation of Javascript easier to the machine language providing quick execution of the code.

Node.js is popular and understand better how Node.js works

The main feature of Node.js are

Asynchronous/Non-blocking thread execution - Every API of the Node.js library is non-blocking. While waiting for a response for something outside the execution chain, the next tasks in the stack are continuously executed.
Event-driven - A server built with Node.js uses a notification mechanism called “Events” to receive and track responses of previous API requests. Event Loop allows Node.js to execute all the non-blocking operations.
Cross-platform compatibility - Node.js is compatible with various platforms like Windows, Linux, Mac OS X, Unix, and mobile platforms.

An Event is Fired specifying that the Time Consuming task is executed and further Processing of the Request can be resumed by the Main Thread.

Node.js runs on Google’s V8 Javascript engine, where web applications are event-based in an asynchronous manner. Node.js platform uses a “single-threaded event loop.”

Node.js handle concurrent requests along with a single-threaded model? Well! “Multi-threaded request-response” architecture is an event loop that is much slower and unable to handle multiple concurrent threads at a time.

The platform does not follow a similar request/response multi-threaded stateless model; instead, it goes by a simplified single-threaded event loop model. As per Node.js developers, a specific library called “Libuv” provides this mechanism known as an event loop. This Node.js processing model is majorly based on Javascript event-based model along with the callback mechanism.

Advantages of Node.JS

Node JS is easy to learn, primarily because it’s based on JavaScript
Node.js is an open source framework with a very active and vibrant community comprised of developers who continuously contribute to its improvement
Since the Node.js is providing the option of non-blocking I/O systems, it relatively helps you to process several requests concurrently
A critical benefit of using Node.js is its ability to handle multiple requests at once
Quicker development of a Minimum Viable Product (MVP) — not a fully-fledged solution, but one with just enough functionality to be well presented on the market
It takes less time to write codes
Node.js has been regarded as a full-stack JavaScript for serving both the client and the server-side applications.

Disadvantages of NodeJS.

The Application Programming Interface (API) keeps on changing at frequent intervals and does not remain stable
The gap between the current growing demand and the true number of experienced Node.js professionals
If you’re keeping a number of queued tasks in running in the background, lookout. You could fall into what Node programmers often refer to as "callback hell"
Compared to other languages, JavaScript does not have a robust and well-equipped library system
When it comes to intensive computation tasks, Node.js doesn’t perform that well.
Node.js developers often struggle with choosing the best package among the thousands of options available.
It doesn’t support multi-threadedM programming.
