Object to Array using Object.keys and Array#reduce

object-to-array.js

var o = {
  a: 1,
  b: 2,
  c: 3
};

Object.keys(o).reduce(function(out, key) {
  out.push({
    key: key,
    value: o[key]
  });
  return out;
}, []); // [{key: 'a', value: 1}, {key: 'b', value: 2}, {key: 'c', value: 3}]

Cool, but it's still and object, just inside the array.

Indeed.
