Slice

slice returns a subset of a string or list. This is equivalent to using the square-brackets slice operator seq[from:to], but with ordinary function syntax.

Arguments

Parameter Name	Default Value	Meaning
seq	string or list	sequence to get a subsequence of
from	number, default	0-based index to the first element to return (if negative, counts from the end)
to	number, optional	0-based index of first element to *not* include in the result (if negative, count from the end; if omitted, return the rest of the sequence)

Example

slice("Hello", -2)		// returns "lo"
slice(["a","b","c","d"], 1, 3)		// returns ["b", "c"]
