when do i uses a synchronus versus asynchronus request?

Question

Varun Agrawal · Answer

There are two ways that Ajax can access the server. These are 
synchronous (wnere the script stops and waits for the server to send 
back a reply before continuing) and asynchronous (where the script 
allows the page to continue to be processed and will handle the reply if
 and when it arrives).
