Update index.js

Hi,

This achieves the same thing as #43 but doesn't put the keys in a weird order (by length), instead it does a lexical sort (i.e. 0-1 A-Z)

['world.lorem.ipsum',
'apple.zebra',
'apple',
'apple.aa',
'world.lorem.dolor',
'0test',
'world'].sort()

Becomes:

["0test", "apple", "apple.aa", "apple.zebra", "world", "world.lorem.dolor", "world.lorem.ipsum"]

Rather than:

['world.lorem.ipsum',
'apple.zebra',
'apple',
'apple.aa',
'world.lorem.dolor',
'0test',
'world'].sort(function(keyA, keyB) {
    return keyA.length - keyB.length
  })

// equals:

["apple", "0test", "world", "apple.aa", "apple.zebra", "world.lorem.ipsum", "world.lorem.dolor"]
