@Armin — That's terrible advice. There's a callback function will fill fire when the data is available. Guessing how long it will take to become available is just stupid. – Quentin Jul 30 '18 at 11:33

But guys any suggestion how I can collect the data in pictureArray? – Kunal Jul 30 '18 at 11:35

See the duplicate question linked in the big yellow box at the top of the page. – Quentin Jul 30 '18 at 11:39

Because you're calling
console.log(picturesArray);
before asynchronous action is finished.
If you'll add this log inside the request callback - you'll get the proper result.

1@Armin — No! Absolutely not! Guessing how long an asynchronous function will take to resolve is stupid. Just use the callback feature which that function provides to tell you when it is done. – Quentin Jul 30 '18 at 11:31
