Why can't I use the data from a GET request?

I want to use the data that is returned from a get request. Nothing I do allows me to use the data outside of the jQuery function.

Here is my sample code.

function getData () {
    var i;
    $.get( 'some_url.php', function( data ) {     
        i = data;
    });           
    return i;
}

console.log(getData());

Here's the error:

jQuery.Deferred exception: getData(...) is undefined ...

How can access the data that is returned and use it elsewhere in my application?

I think `$.get` is async. So by the time `i` is updated, it already `return i` which is undefined. – Milan Chheda Aug 01 '17 at 11:02
`$.get` is an asynchronus function.Async functions don't return values – Manos Kounelakis Aug 01 '17 at 11:03
This will not work as it's an async request. Alternatively, try using promises for better readability – carlo Aug 01 '17 at 11:05
You can use `$.ajax` with .`async: false` – Milan Chheda Aug 01 '17 at 11:06
