Advantages of AJAX
Reduce server traffic and increase speed
The first and foremost advantage of Ajax is its ability to improve the performance and usability of web applications.
To explain more detailedly, Ajax techniques allow applications to render without data, which reduces the server traffic inside requests. That being said, web developers can lower the time consumption on both side’s responses significantly.
As a result, your web’s visitors will never have to see a white window and wait for pages to refresh with Ajax implementation.
Enable asynchronous calls
Ajax benefits web developers in how its framework can be used for lazy loading. Those who don’t know what Lazy Loading is are an optimization technique that’s widely used for online content.
In essence, Ajax allows its users to make asynchronous calls to the web server without reloading the whole web page. As a web visitor, you don’t have to wait for the entire page to load entirely in order to access the entire page content.
Disadvantages of Ajax
We’ve just listed out all the areas where Ajax can show its great potential in implementation. Let’s move on to some possible drawbacks you can meet when using Ajax.
Open-source. View source is allowed, and anyone can view the code source written for Ajax, which makes it less secure compared to other technologies
Search Engines cannot index Ajax pages can not be indexed by Google as well as other search engines
The usage of Ajax can cause difficulties for your web pages to debug as well as make them prone to possible security issues in the future
Users will find it challenging to bookmark a specific state of the application due to the dynamic web page
From the users’ perspective, when you click the back button on the browser, you may not return to the previous state of the page but the entire page. This happens because the pages with successive Ajax requests are unable to register with the browser’s history
