Access non-numeric Object properties by index?

Question

If I have an array like this:

var arr = [\'one\',\'two\',\'three\'];

I can access different parts by doing this:

console.lo         


        

Answer 1

Get the array of keys, reverse it, then run your loop

  var keys = Object.keys( obj ).reverse();
  for(var i = 0; i < keys.length; i++){
    var key = keys[i];
    var value = obj[key];
    //do stuff backwards
  }
