Node js advantages and disadvantages

There is no doubt that JavaScript, specifically Nodejs, is one of developers' widely used client-side programming languages. JavaScript is employed for front-end development and is quite handy for building cross-platform applications.

JavaScript also has an excellent reputation for its usage in other popular platforms such as PhoneGap, Apache, NativeScript, Accelerator, Titanium, and more.

In the current area, the application of JavaScript has widened, and now it is also being utilized as server-side programming. Nodejs has played a crucial role in this significant shift in web development.

Nodejs manages browser requests and offers asynchronous, event-driven I/O APIs to fetch the results not only speedily and accurately. It runs a single-threaded event-based loop; hence all the executions become non-blocking.



Here, it is essential to note that:

Node is a server and not a framework.

Node wrappers over JavaScript V8 Runtime are made in C and not in JavaScript

It runs in a single thread with a callback concept.

Advantages of NodeJS

Here are the advantages of using Nodejs as server-side programming:

1. Easy to learn:

Most developers have a good grasp of JavaScript, for it is one of the most popular programming languages.

The developers already good in JavaScript find it easy to use Node.js at the back end. It is pretty easy to learn Nodejs and consumes less time.

2. Supported widely by Google Chrome:

The search engine is empowered by Node.js, which aids in the front-end development and dramatically impacts the back-end. In addition, Nodejs is supported by the Google V8 engine, which has the power to execute simultaneously in the front end using JavaScript.

3. Node.js offers easy scalability:

One of the critical benefits of Nodejs is that it makes it easy for developers to scale the application in horizontal and vertical directions. The application can be mounted in a horizontal dimension by adding extra nodes to the current system.

Furthermore, Node.js also allows adding extra resources to a single node during the vertical scaling of the application. Hence, NodeJS is highly scalable and offers more excellent options than other JavaScript servers.

4. Full-stack JavaScript:

Node.js is regarded as a full-stack JavaScript for serving server-side applications and the client.

The benefit of using Nodejs is that you need not hire Node JS developers in India for front-end and back-end, which saves you valuable money and time.

5. Offer High Performance:

As mentioned earlier, Node.js interprets the JavaScript code through Google's V8 JavaScript engine. The engine compiles JavaScript code directly into the machine code. Hence, it becomes easy to implement the code. Moreover, it can be done quickly and in an effective manner.



Disadvantages of using Node.js

1. API is not stable:

One of the critical problems developers encounter while working on Node.js is that the Application Programming Interface keeps changing at frequent intervals and does not remain stable.

At times, you will see a new API with multiple backward-incompatible changes. As a result, developers must make changes in the accessible code bases to remain in tune with the latest version of Node.js API.

2. Library Support System is not robust:

JavaScript does not have a robust and well-equipped library system compared to other languages.

This makes it difficult for developers to implement everyday programming tasks using Node.js.

3. Asynchronous Programming Model:

If you want to boost the scalability of the application, the requirement is that the application should adopt an asynchronous programming model.

However, developers find this model to be more difficult as compared to linear blocking I/O programming.



Conclusion

Node.js offers a lot more advantages to developers than its disadvantages. Moreover, it has extended the area of JavaScript applications and can be utilized for both front-end and back-end servers.

With the progress of time, more and more businesses are adopting Node.js, and it has resulted in positive results for their business.

A Guide To Social Media Algorithms & How They Work

Image
 Why do so many marketers keep asking, “How do social media algorithms work?”  However, SimilarWeb's above data only applies to desktop and mobile web channels. YouTube's search and recognition systems address this challenge by paying close attention to: what viewers see.  what they don't see or watch.  How much time do they spend watching or scrolling?  What do they share and like/ follow and unfollow?  How does the Facebook algorithm work today? The Facebook algorithm is a system where, after checking some guidelines, the platform decides that it needs to show certain content in your followers' news feed.  As the Facebook portal reveals , "this resource determines which posts appear in your news section and in what order by predicting what you're most likely to be interested in or interact with. And that requires a trained system that distinguishes what a given person likes and doesn't like in order to offer the best quality content.  Well, has...
