I have an associate object.
records: {
   '15/07/2017': [],
   '16/07/2017': [], 
}
I want to add an extra item to the object, at the present moment I am having to use:
Vue.set(self.records, '17/07/2017', []); 
The problem that I have is that the record is added at the end of the list, while I want the record to go to the front of the list. How can this be rectified?
