The synchronous and Asynchronous type requests in AJAX are used based on the request priority of the web server request. They should be carefully configured to make the server respond to the user based on the user requirement. The synchronous request waits for the server’s response after requesting to proceed with the next part of the script execution, which is crucial in a fast response mechanism. This should be avoided frequently to make the server highly responsive. Wherever the synchronous request mechanism is essential or inevitable, it should be used.
