You are clear, but I think that there is a misunderstanding problem. The order of elements in an array is important. In fact, each element in the array is in the same order as you specified.
The order of properties in an object, on the other hand, is unspecified and can change from one JavaScript implementation to the other. When talking about objects and properties, the only important thing is that the same properties (associations between a name and a value) are retained, even if the relative order is changed. This is what the others told you until now, I hope that another explanation from a different guy helps you refreshing your mind. 2014-05-03 17:06 GMT+02:00 Alejandro Paciotti <[email protected]> : > Sory Angel, maybe I can not explain properly. > > The problem is with each elements in the *data *object that are recorded > in reverse order. > > [image: Imágenes integradas 1] > > I admit I conceptually confused with arrays and objects, but *data is an > array* that contains *objects* of 7 elements. > > The problem is with the objects that are recorded invested. > > *Periodo, Total, CobradoSegunContrato.....
