» slice Function

slice extracts some consecutive elements from within a list.

slice(list, startindex, endindex)

startindex is inclusive, while endindex is exclusive. This function returns an error if either index is outside the bounds of valid indices for the given list.

[
  "b",
  "c",
]
  • substr performs a similar function for characters in a string, although it uses a length instead of an end index.
