This means that users can interact with your website or app while it communicates in the background, providing them with content they might not otherwise see if they had to reload a new page each time.
For example, when creating a shopping cart on most e-commerce websites, all items are added as soon as they’re selected because this interaction happens via “synchronous” pages where every click loads additional content either on top of what was there before or replacing it altogether (i.e., adding another layer).
Is AJAX good?
AJAX is good if you want your website to be more responsive and interactive. It makes users feel like they can do anything without having to reload the page for every interaction, which gives them a better experience on the site.
However, it does have some drawbacks: AJAX needs additional server resources and there are security risks associated with using this type of programming for certain tasks such as when transmitting sensitive data or financial information (though these issues can often be mitigated by taking appropriate precautions).
Benefits of using AJAX in web development
AJAX has many benefits, including:
- Improved user experience – web pages are able to update content without reloading the page for every interaction. This gives users a better experience on the site and also helps developers because it is faster than having to reload the entire webpage over again in order to see updates made by other changes they may have made to their code.
- Reduced bandwidth requirements when displaying dynamic data – since AJAX doesn’t require you to load up an entirely new webpage each time (instead loading just certain elements), your server can handle more requests per second with less strain put onto its resources. It’s important that your website stays fast while being easy-to-use so people will keep coming back!
- Increased flexibility – developers can dynamically add new content to webpages without having to refresh the whole page. For example, if a user is viewing their inbox and they see an error message about not being able to send an email, clicking on that link could take them directly into your “reset password” form while preserving what was already visible in the original window – rather than reloading the entire webpage which would make things like scrolling through messages disappear.
- Improved usability for site visitors – AJAX enables website administrators to provide more interactive features by removing some of the frustrations associated with traditional static websites. The end result? Site visitors spend less time waiting for pages or images to load!
AJAX vs JSON
AJAX and JSON are two different languages. AJAX is a way of programming websites, while JSON is the type of data file that webpages request from your server in order to display content on their page.
