Get content into variable

Question

I get only [] in console. The function is asynchronous, and the console.log runs before function(content). I understand that, but, I can't resolve it.

async function fja() {
    var mydata = [];    

    await Neutralino.storage.getData('notes', function(content) {
        var mydata = content;
    })

    console.log(mydata);
};

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) — Adam Azad, Dec 05 '20 at 14:50

You can declare the variable outside the function:

let data;

Then, inside the function:

data = content;

Could you update your question to show how you've done it? – Daniel_Knights Dec 06 '20 at 10:57
if I put console.log in new function and start it manually then i get data. – Ante Olić Dec 06 '20 at 11:29
You've done it correctly, but, if `Neutralino.storage.getData` is asynchronous you'll have to await the results before you can log it to the console – Daniel_Knights Dec 06 '20 at 11:32
If `Neutralino.storage.getData` is *inside* a function, you can make it `async` and then `await Neutralino.storage.getData`. If not, try adding a [`.then()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then) onto the closing bracket. – Daniel_Knights Dec 06 '20 at 11:34
I try evrthing but i cant get console.log(mydata). its always empty – Ante Olić Dec 06 '20 at 18:01
You have to show me how you're doing it or I can't help you. If all you've done is the updated code in your question, that won't work as it's asynchronous – Daniel_Knights Dec 06 '20 at 19:22
I have updated my questions with newest code – Ante Olić Dec 06 '20 at 19:37
It should be `myData = content` without the `var` – Daniel_Knights Dec 06 '20 at 19:39
it is still []. – Ante Olić Dec 06 '20 at 19:51
[It should work](https://jsfiddle.net/3qyj06mh/), there must be another reason. – Daniel_Knights Dec 06 '20 at 19:55

OK! thank you very much for your time. I will ask author of neutralinojs. – Ante Olić Dec 06 '20 at 19:56
Author of neutralinojs told me that Neutralinojs uses ie11 component on Windows. await and Promises are not suported. – Ante Olić Dec 07 '20 at 16:10
