Why this code works ?

My question is why the displayPhotos function works before $.getJSON runs?

$.getJSON sends a request to a server, which is likely to be slower returning than the time that the rest of the code in your script takes to be executed.

Remember a few lessons back, you were told that AJAX queries return at different times, and you can't predict which one comes back first? This is a good example.

Note: your question was a little vague - this is the best I can do to answer it without you providing more information. If you're experiencing a specific problem with this challenge, can you elaborate please?

Note, that the A in AJAX stands for "Asynchronous" - and this is exactly what it means.
