Example of using Object.entries

object.entries.js

// http://www.dogbreedchart.com
const dogShedding = {
  foxhound: 3,
  'basset hound': 2,
  beagle: 3,
  'bernese mountain dog': 1,
  poodle: 5,
}

// 🔥🔥

// Object.keys is an ES 5.1 feature (supported in IE9)
Object.keys(dogShedding).forEach(key => {
  const value = dogShedding[key]
  // etc.
})
// We've been using Object.keys to do this for a while...

// 🔥🔥🔥🔥

// Just need the value? Save yourself some trouble
// and use Object.values instead!
Object.values(dogShedding).forEach(value => {
  // etc.
})
// Object.values is an ES2017 feature (polyfillable in IE)

// 🔥🔥🔥🔥🔥🔥🔥🔥

// Need both key and value? Use Object.entries and destructuring
Object.entries(dogShedding).forEach(([key, value]) => {
  // etc.
})
// Object.entries is also ES2017 feature (polyfillable in IE)
// destructuring is an ES2015 feature and transpileable by
// Babel with babel-preset-env
