Why there is no one has mentioned Object.keys() ?

you can get Array of Object's properties ordered as it is, then you can reverse it or filter it as you want with Array methods .

let foo = {
  "one": "some",
  "two": "thing",
  "three": "else"
};

// Get REVERSED Array of Propirties
let properties = Object.keys(foo).reverse();
// "three"
// "two"
// "one"

// Then you could use .forEach / .map
properties.forEach(prop => console.log(`PropertyName: ${prop}, its Value: ${foo[prop]}`));

// PropertyName: three, its Value: else
// PropertyName: two, its Value: thing
// PropertyName: one, its Value: some
