How to convert an Object to an Array of key-value pairs in JavaScript

Question

I'd want to transform the following object:

{"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}

I want to transform the following object:

[[1,5],[2,7],[3,0],[4,0]...].

In JavaScript, how can I transform an Object to an Array of key-value pairs?
