Is there a way to sort/order keys in JavaScript objects?

Question

For example the following

var data = {
    \'States\': [\'NSW\', \'VIC\'],
    \'Countries\': [\'GBR\', \'AUS\'],
    \'Capitals\': [\'SYD\', \'MEL\']
}
for

Here's a one-liner to sort an object's keys using lodash

_.chain(obj).toPairs().sortBy(0).fromPairs().value()

With your example data:

var data = {
    'States': ['NSW', 'VIC'],
    'Countries': ['GBR', 'AUS'],
    'Capitals': ['SYD', 'MEL']
}
data = _.chain(data)
  .toPairs() // turn the object into an array of [key, value] pairs
  .sortBy(0) // sort these pairs by index [0] which is [key]
  .fromPairs() // convert array of pairs back into an object {key: value}
  .value() // return value
/*
{
  Capitals: [ 'SYD', 'MEL' ],
  Countries: [ 'GBR', 'AUS' ],
  States: [ 'NSW', 'VIC' ]
}
*/
