Question

Looking at the following code, does theme[sprite].img get nested inside result[definition].data (as theme[sprite].img is inside theme[sprite]) as well as .img becoming its own element in result[definition]?

result[definition].data = theme[sprite];
result[definition].img = theme[sprite].img;

And if that is the case, what would happen if result[definition].data.img was deleted, would that also delete result[definition].img and even theme[sprite].img?

Thanks.

Answer 1

If you delete result[definition].data.img, then theme[sprite].img will be deleted too, because result[definiton].data and theme[sprite] are exactly the same single object. result[definition].img will retain its value beacuse result[definition] is separate object that have in its .img property copy of .img from another object.

This is not related in any way to nesting though. You simply reference the same object.
