Does this answer your question? [How do I return the response from an asynchronous call?](https://stackoverflow.com/questions/14220321/how-do-i-return-the-response-from-an-asynchronous-call) — Tân, May 01 '20 at 10:07
Your console command runs *before* the ajax reply arrives in the browser. The ajax request is async, that's why you have to use `.then()` and pass a callback function. Example: https://jsfiddle.net/yfqckwzo/ — , May 01 '20 at 10:09

javascript is an asynchronous programming language and you are doing an ajax call so on ajax call by default async will be true so you have to try with async : false on ajax call. Just give try may be it will give luck
