Quick code challenge - sorting on four

sort-on-4.md

How do you sort a list of words on the 4th character of the word? What"s the shortest solution?

[ "strawberry", "helicopter", "wales", "acorn" ]

should be:

[ "strawberry", "wales", "helicopter", "acorn" ]
// str_a_berry, wal_e_s, hel_i_copter, aco_r_n

You can use this dataset to test.

Something along the lines:

arr.sort((a, b) => {
  if (a?.[3] && b?.[3]) return a[3].localeCompare(b[3])

  return a.localeCompare(b)
})

What happens when the word is smaller than 4 characters? I'm using a regular sort method, but I'll leave that to you because I don't know your exact requirements.
