Node.JS and why you should use it

JavaScript is undoubtedly one of the most popular programming languages by web developers and designers. It makes it easy to creating interactive and dynamic spacesproviding an optimal user experience.

In the beginning, JavaScript could only be used with the tag, so programmers were forced to work with different languages and frameworks... until Node.JS came along.

But, what is Node.JS and what is it for? In this article, we tell you more about this cross-platform runtime environment for one of the most popular and popular mobile programming languages most important at the present time.

What is Node JS?

First of all, it should be noted that Node.JS is a fundamental and very popular tool for the development of web applications. In fact, it is used by almost every major brand: Microsoft, NASA, Netflix, PayPal, LinkedIn... 

Node.JS is the cross-platform server-side runtime environment that interprets the JavaScript language. In this way, the programming process is optimised, since thanks to Node.JS, the same language can be used on both the client and server sides, eliminating information asymmetries.

In addition, Node.JS is open source, has a "Single Threaded Event Loop" architecture, and deals with creating scalable applications. All this in order to be able to handle different clients quickly and simultaneously. Thanks to the latter, there are no process bottlenecks.

How Node.JS works: key features

In response to the question of what is Node.JS and why should you use it?The following features or functions of Node.JS are worth mentioning:

• Built on Google Chrome's V8 engine: First of all, this is a good reason why you should use Node.JS. This engine is one of the most advanced in the JavaScript language, so its library is very fast when executing code.
• Efficiency: Node.JS is characterised by its efficiency when handling events. This is because this execution environment is very light, it weighs very little, which also improves its speed.
• Event-driven: Since Node.JS does not have to wait for the API to return data, the server employs an event notification system. This allows it to get a response from the API (or application programming interface) above.
• Scalability: To run an application with Node.JS, you need to know that it is a very scalable mechanism. The server is non-blocking, so it compares well with other servers.
• No buffering: That is, Node.JS does not generate data, so that the data remains buffered.

And if you still don't know what Node.JS is and why you should use it, here are 7 reasons why you should use this cross-platform runtime environment.

Why use Node.JS: 7 reasons to use it?

Find out what Node.JS is and why you should use it. These are our top 7 reasons:

1. Various servers

Node.JS can run on a wide variety of servers. Without going any further, it is present in both Microsoft Windows as well as Mac OS X and even Unix..

2. Exchange between professionals

As it is open source, it encourages the exchange between the work of the different specialists in the field. software development. Therefore, something very positive is created: a collaborative community between professional colleagues.  

3. Reduce times

By optimising programming processes and data transfer between client and server, times are also decreasing and in a considerate way, too. 

4. For high traffic applications

Node.JS is highly recommended for apps with a lot of traffic and events. This is the case, for example, of the social network Twitterwhere thousands of tweets are generated every day.

5. Performance

On the other hand, to the question of what Node.JS is and why you should use it, this section is key: its performance.

Programming experts have been pleasantly surprised by this quality. The quality generated is very noticeableIn addition, the margin of error has also decreased significantly.

6. For real-time apps

Indeed, video games are a good example of this. Node.JS is also recommended for online chats.

7. Creation and innovation in applications

In short, Node.JS allows you to innovate in the invention of applications, thanks to its relevant scalability. A whole new universe has opened up for programming professionals, allowing - for example - a large number of users to be connected at the same time.
