if there is going to be a lot of processing, you might be better off copying the data.
The JSON structure does incur some processing overhead.

A regular loop is simplest:
MyArray : TMyArray;
MyJSONArray : TJSONArray;
i : Integer;
MyJSONArray:=// Get the array...
For I:=0 to MyJSONArray.Count-1 do
// Now work with myarray
Use the correct property for whatever type the array contains.
