Now, these days Node.js is mostly used for web design and development. Mostly Web design and development company are used Node.js. In this blog, I will explain to you Node.js and its Benefits.

What is Node JS?

Node.js is an open-source, cross-platform, JavaScript run-time environment that executes JavaScript code outside of a browser. Node.js was released on May 27, 2009, by its author “Ryan Sahl”.

As you know Node.js is an open-source server environment so It’s free to use. Node.JS runs on various platforms like Windows, Linux, Unix, MAC OS X, etc, Node.js has used JavaScript on the server.

The Node.js can generate dynamic page content and It can create, open, read, write, delete and close files on the server. Node.js can collect form data and add, delete modify data in your database.

The Node.js files contain tasks that will be executed on certain events and It is a typical event is someone trying to access a port on the server.

A Node.js files must be initiated on the server before having any effects and Node.js files are save with the .js extension.

Node.js is a server-side platform. Which builds on the JavaScript engine of Google Chrome. Node.js also provides a rich library that contains many JavaScript models. With the help of which we can easily develop any kind of web application.

Node.js = Runtime Environment + JavaScript Library

Features of Node.js

Node.js has very important features due to which Node.js is becoming the first choice of all software development company. Listing some features below.

All the APIs and libraries of Node.js are asynchronous, which means no-blocking. This means that the node.js Based server does not wait for API to return data.

Whenever Node.js code is built, it is on Google Chrome server V8 JavaScript engine Due to which the code gets executed very quickly in the library of node.js.

Node.js Which always has a single-threaded model does it with all events. Event mechanism always helps in the response of the server which makes the server very fast without blocking.

Node.js application never buffering, These applications simply provides output in chunks.

Concept of Node.js

To understand the concept of node.js, I am applying an image below, by looking at it, you will understand how node.js works.


Where we use Node.js?

We can use Node.js to create many applications, below are some applications in which we can use Node.js.

1. I/O bound the application.
2. data streaming Application.
3. Data-intensive Real-time Application.
4. JSON APIs based application.
5. Single page application.

Is the Node.js a programming language?

Node.js is an environment that runs JavaScript outside the browser box. Javascript uses the browser for running. I know JavaScript already runs outside of the browser like the engine of Windows. This is a common task that uses scripting on its own but does not use backends for websites.

Now let me show you how to run node.js. Before running node.js, we have to run jus interpreter in the command line. Most people do not know this step.

In Node.js an interpreter includes. or it extends the language class library with newly built-in classes especially for handling file and network I/O with a preference for asynchronous patterns.

For the security reason, JavaScript doesn’t include the I/O files in the browser. And it also does not do networking tasks because browser works. JavaScript is built for any browser outside of DOM.

Node.js Which does not include any specific library for working of DOM. There are some models here that do all these things.

So which is the original idea of Node.js Which is to set up the web services first and the repair service which makes its server very fast?

The thing to note here is that:- The code part of Node.js is written in C and libuv and the event handling pattern to be built in the file descriptor handling. The underlying javascript interpreter for v8 is also written in C.

If you run the same file on V8 then you will get an error which is non-exhaustive classes.

What is Node.js vs JavaScript?

JavaScript is a programming language that runs in a web browser. The same node.js is an interpreter and running environment for JavaScript, Which holds many important libraries.

JavaScript is basically one standard defining programming language, It runs in any browser environment. This is a very strong language that web designing and development companies use in making most web applications.

Node.js has a lot of relative libraries which is in the journal purpose programming language of JavaScript. It is a kind of environment and interpreter that represents JavaScript and runs any JavaScript program.

Now Its time to head to head comparison.

JavaScript is a programming language that runs on a web browser in a proper browser engine. Node.js is an interpreter and environment for JavaScript, along with some specific libraries that do this separately to the Java Script program.

JavaScript Mainly uses the activity of client-side activity for web applications. And Node.js is used for accessing and performing any non-blocking operation for any operating system.

Javascript runs for any engine like spider monkey(firefox) Javascript core(safari) V8( Google Chrome). Node.js runs on V8 engine that is mostly used in google chrome.

So now you must have understood what the basic differences are in both.


Is Node JS frontend or Backend

Node.js is a runtime environment, which helps the user to choose whether to do it in the frontend or do it in the backend.

As its environment is what the features of JavaScript do in the form of it, And runs it in the web browser, then it is done in the backend. As there is another feature in automating the routine task, due to which we can use it in front-end as well.

In short, it can be used for both! Hope this makes things clear! Node.js is used for web design and development.

If you want to read and understand node.js and in detail, then you have to go to the website of node.js w3schools, you will get complete details.

If you need documentation of Node.js, then you can download from here. You can learn lots of things, APIs, the Library, and so many things.

If you want to run the example of Node.js, you will find it on the website of w3schools and you can run it by watching it.

Freelancer Groups are already created some of the web application using Node.js. Now, these days Mostly Web designing or Development companies are using the Node.js and created so many web application.
