___ ___ erkimt Sort an array within an object, entering all the hierarchies of the same ______ qstntxt ___

I own an object containing several arrays within it. And these arrays contain other objects that contain a %code% field that I would like under each hierarchy to be sorted by that field. And I would like to go through each sub-menu inside the objects and sort them as well.

%pre%

Since %code% changes the array directly you can do this:

%pre%

Example:
