Returning a value from a Promise

Question

I would like to call the Google Maps Geocoding API using a Promise like this:

function makeGeoCodingRequest(address,bounds)
{
    /*
        Input parameters         


        

Answer 1

If you want your code to wait until the asynchronous action is completed before continuing (BAD IDEA - the page will freeze while the request is completing) then add async: false to the ajax request's parameters.

My recommendation, though, is to have makeGeoCodingRequest return nothing directly - and simply give it an extra argument, requestCallback so that its caller can pass in a function that will be called when the data is available. Call that function, with the resulting data, inside of your promise.then function.
