Ah, thanks. I thought that myArray[“gpx”] was an array (since it’s the ‘top’ key of a multidimensional array), so therefore an object.
I think my mental model of arrays is wrong: roughly my model is array[key1][key2] etc means an array which has a series of arrays at the level of key1 each of which is indexed (keyed) by key2, etc. I suppose I’m wrong.
