// Note: The contents of the array were copied.
// If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
// For example:
CkJsonArray_AddIntAt(jarr,-1,2020);
Memo1.Lines.Add(CkJsonArray__emit(jarr));
// Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Luther"},2020]

Memo1.Lines.Add(CkJsonObject__emit(json));
// Remains unchanged: {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}
