Advantages and Disadvantages of Ajax | Definition, Pros and Cons, Benefits and Drawbacks

Advantages and disadvantages of Ajax 2022: Today’s world is the world of technology and computers. We use computers and this technology almost in daily life. Many languages have been introduced into computers that have made our life easy and simple. Languages like C, C++, HTML, Java, and python. All these have contributed to the development of humans by making them technologically advanced. Web pages are nowadays most accessed by people as people are in search of data and various other entertainment facts. Therefore computer analysts seeing this as an opportunity have found various technologies that are used for making various web applications. One of these is Ajax. It is a combination of java and XML. Let us know more about Ajax.

What is Ajax? How Does It Works?

Ajax stand for Asynchronous Javascript and XML. The name suggests that it is a combination of JavaScript as well as XML languages for computers. It uses web technologies on the client-side for asynchronous web applications and is a set of web development techniques. With the help of Ajax, a computer user can send or retrieve data asynchronously without disturbing the working of a current web page. It can change the content of web pages without reloading the entire page. Ajax first appeared in March 1999  and its extension is- .js. It is a programmable concept more than a technology. It also uses HTML and CSS languages to mark up and style information. It is not a new technology but a new way to use the existing technology.

What are Javascript and XML?

Javascript is a text-based programming language used by programmers for creating dynamic web content, browsers, and applications. It is used on both client-side as well as server-side so that the web pages could be made more interactive. While XML is like an HTML but doesn’t have any predefined tags to use but has there own tags particularly according to the use of users.  It is the easiest format that stores data that is easily storable, searched, and shared. Both Javascript and XML are used in Ajax to make it a more interactive and easy interface.

Advantages of Ajax

Let us briefly see the advantages of Ajax.

• The processing of data is asynchronous: Ajax allows retrieving or sending of data without reloading the whole page. Therefore users can make asynchronous calls to the web browser. For optimizing the web content a technique known as lazy loading is used. This allows only the required content to reload and delay the rest. This not only improves web page loading but also increases user interfaces and conversation.
• Many browsers can be used at a time: It is faster, user-friendly, and engage the user by allowing multiple updates on the web. This way multiple browsers could be operated at a single time. It is also responsive to the user’s questions and therefore many browsers allow to open many windows at a time.
• Improved response time: As Ajax help in optimizing the web content thus the response time is improved to a much extent. It improves the interaction with users and also server traffic is removed.
• Doesn’t require third-party software: The need for any external software is not necessary in the case of Ajax as the software is already present in the combination of JavaScript and XML. So third-party software is not required in Ajax.
• 5. Improve web application performance: With increased speed and improved response time the performance of web applications increases. The favourable condition to establish the interface with the user has been established. Therefore the performance and work speed of the application is increased.
• Form validation: Ajax provides precise and immediate form validation. In the traditional approach, one has to submit the form for validating it. In this, the process is slow in the traditional approach while ajax is much faster. Therefore form validation is better in Ajax.

Disadvantages of Ajax

Let us briefly see the disadvantages of Ajax.

1. 1 No indexation of Ajax pages: Google or other Search engines cannot index the Ajax pages. This became one of the disadvantages to users as they may not easily find the pages.
2. Less secured: Since anyone can access the code written for Ajax therefore it becomes an open source to everyone who wants to access which makes it less secured.
3. Difficult in debugging: There is no good tool available for debugging Ajax. Javascript alone doesn’t have any tool to debug. And since all the responses and requests are managed by javascript itself therefore debugging is difficult.
4. Dependency on Javascript: The whole codification of Ajax is done with the help of Javascript and XML. And since there is no tool available to debug therefore dependency on javascript is one of the disadvantages of Ajax.
5. Dynamic web pages: Since there is no indexation of pages the user might get confused. They are unable to bookmark a particular state of applications because of these dynamic web pages.
6. If users use the back button then the entire previous page is visible: If a user has made multiple and successive Ajax requests then it is not able to register with the browser’s history and thus if a user wants to go to the previous state of a page then the entire page is reloaded.
7. More data is consumed: Since data is written on codes therefore the data consumption is more. Therefore the user finds it difficult to manage the Ajax pages.
8. No javascript is installed then no access to Ajax: Ajax is based on the programming language Javascript thus if a system is not supporting javascript then it cannot access Ajax.
