Get last key of an object and insert in first position of keys

Question

I have this object structure in Javascript:

{
  2015-08:367,
  2015-09:381,
  2015-10:390,
  2015-11:400,
  2015-12:396,
  PAYOR:"PCP",
}

And need get this result:

{
  PAYOR:"PCP",
  2015-08:367,
  2015-09:381,
  2015-10:390,
  2015-11:400,
  2015-12:396,
}

Why does object order matter? You usually pick values out by keys, — pmkro, Mar 09 '18 at 21:32
That's not a valid object, also the ordering of keys inside object can't be reliably sorted. — cyr_x, Mar 09 '18 at 21:32

Order of keys in JS objects is not guaranteed to be stable and can be implementation dependent. As pmkro said, don't use it
