in .ajax calls, is async: true assumed by default?

Question

Some of the code I've seen specifies async:true and other code async:false. If I don't declare async at all, does it default to true, so ajax calls are by default asynchronous?

Answer 1

Looking at the documentation of jQuery.ajax (quoting) :

By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false.
