Ajax Tutorial

In this tutorial for beginner, We'll cover the basics of Ajax. We will begin to explore different things connected with it, learn exactly what it is, how it works.

This ajax tutorial for beginner article aims to familiarize front-end designers and new developers with AJAX.

It gives Web developers lots of ways to enhance the user interface and the efficiency of their websites.

Before, starts the Ajax tutorial for beginners we assume that you are familiar with front-end technologies, such as HTML and CSS.

AJAX stands for "JavaScript and XML asynchronous" This is not a single technology, but a modern one. It's actually a group of existing technologies ( i.e. HTML, CSS, JavaScript, XML, etc.) that come together to build modern web applications.

It allows you to asynchronously send and receive data without reloading the Web page. It's quick.

A client uses the XMLHţRequest or XHR API to apply to a server. Think of the API ( Application Programming Interface) is a collection of methods that define the protocol rules between the two parties involved. Notice, however, that incoming AJAX request data may be in any format, and not just in XML format.

You will appreciate that it is an important concept for the modern web with this in mind. We are able to control the amount of data downloaded from the server by developing AJAX-powered applications.

Nodejs Tutorial

This tutorial is designed for software programmers who want to know the fundamentals of Node. Js and its conceptual architecture. This Nodejs tutorial will provide you with the advantage and disadvantages of nodejs programming.

What is Nodejs?

Node. Js can be described as a JavaScript framework or runtime environment developed at the Google Chrome JavaScript V8 engine that is dynamic, cross-platform, and open-supply. Node. Js, which was developed using Ryan Dahl in 2009, was, to begin with, applied as a scripting language for the consumer-facet. Nowadays it is used to execute JavaScript code and scripts to build dynamic net pages that run server-aspect. The Node. Js ultramodern model is 10.10.0.

Advantages of Nodejs

Let's get downwards to the major advantages of using Node. Js as programming on the server-side:

•  Node.Js gives an Easy Scalability

One of Node.Js' key advantages is that the builders can easily locate the programs in both horizontal and vertical directions. The packages can be horizontally scaled, by adding additional nodes to the existing machine. 

•  Easy Learning 

Because JavaScript is definitely one of the most popular programming languages, the maximum number of front-end constructors has a very powerful hold on it.

•  Node. Js is a Single Program Language

Node. Js provides the privilege of writing server-side programs in JavaScript to the constructors. In addition to the back-end internet application in JavaScript, this allows the Node. Js developers to write each front-end the use of a run time environment.

•  The Use of Fullstack JS

Node. Js appeared as a full-stack JavaScript to support the client and server-aspect applications for each.

•  Known for High Offers

Earlier it was reported that Node. Js transforms the JavaScript code via the Google V8 JavaScript engine. This engine follows the JavaScript code through the gadget code immediately. That makes it less complicated and faster to effectively put the code into force.

•  Node. Js is extremely extensible

It is known that the Node. Js is enormously extensible, which means that you can customize and even render bigger Node. Js according to their needs.

Drawbacks of Nodejs

•  Application Programming Interface (API)

The Application Programming Interface ( API) continues to convert at frequent intervals and does not continue to be stable is one of the key problems that maximum builders face.

•  Does not have a good supporting library network

In comparing various programming languages, JavaScript does not have a well-organized and robust library structure.

•  Asynchronous Interface Programming

If you want to make the programs more scalable, adoption of the asynchronous programming version is the necessary necessity.

However, many developers may find this version of programming more difficult compared to the linear programming blocking off I / O.
