code: function toArray(obj) {
      var key, val, arr = [];
      for (key in obj) {
          val = obj[key];
          if (Array.isArray(val))
              for (var i = 0; i < val.length; i++)
          arr.push([ key, val[i] ]);
          else
              arr.push([ key, val ]);
      }
      return arr;
  }
docs: Maps object to bi-dimensional array  @example toArray({ foo: 'A', bar: [ 'b', 'B' ]}) will be [ ['foo', 'A'], ['bar', 'b'], ['bar', 'B'] ]
