 }
 ]
 }
 ]
}

Now what i really need is to get the certification only from the US, so i would get PG-13. But for some reason whatever i do seems to just return undefined and will not match with the US, the only way i got this to work was showing only [6] which is fine, but US will not always be #6

How can I achieve this?

• Erubiel: I think you are missing your javascript code for this question to be clearer.

Answer 1

You can use Array.find() to find the object with US certification. The Array.find() method will find a value that matches the given condition. In your case iso_3166_1 should have value of US.
