  //      note 1: Splits a string into consecutive chunks of at most size, like Kotlin text chunked.
  //   example 1: chunked('kotlin', 2)
  //   returns 1: ['ko', 'tl', 'in']
  //   example 2: chunked('abcdefg', 3)
  //   returns 2: ['abc', 'def', 'g']
  //   example 3: chunked('', 4)
  //   returns 3: []
