I want to convert an object like this:
{\"1\":5,\"2\":7,\"3\":0,\"4\":0,\"5\":0,\"6\":0,\"7\":0,\"8\":0,\"9\":0,\"10\":0,\"11\":0,\"12\":0}
The best way is to do:
var obj ={"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}
Object.entries(obj);
Calling entries, as shown here, will return [key, value] pairs, as the asker requested.
Alternatively, you could call Object.values(obj), which would return only values.
