Flatten an Array

Flatten an arbitrarily nested array into one flat array.

Examples

  • flatten([1, [2, [3]]]) → [1, 2, 3]

Constraints

  • Keep the required function name so the tests can find it
  • Return a value instead of only logging it
  • Do not mutate inputs unless the challenge asks you to
