Given text = "planet", what does text.slice(1, 4) return, and what happens to text?

  1. lane, with text unchanged
  2. lan, with text unchangedRespuesta correcta
  3. lan, with text shortened
  4. pla, with text unchanged

Explicación

slice starts at index 1 and stops before index 4, producing "lan" while leaving the source unchanged. Including the character at index 4 would wrongly treat the end boundary as inclusive.
