A scenario I am facing involves a function that is set to execute jquery.ajax and return it as a promise for future processing.
However, in certain cases, the function possesses enough information to proceed synchronously without triggering the ajax call. Nonetheless, it must still return a promise in order to adhere to its agreement with callers. What would be the most appropriate way to handle this?
For example:
function f(x) {
return x?
$.ajax({url: "http://myServer", data: x, ...})
: /* what should be here? */;
}
