Subject: Re: How does slice work?

You pick a starting point to slice and then a number of items to
slice. For example, if you write:

"0123456789".slice(i, size)

then you will slice starting after the `i`-th character, and for
`size` more characters, or until the end of the sequence, whichever
comes first. For example,

"0123456789".slice(5, 3)

will yield "567". We start at "5" because the i = 5th character is
"4", and "5" is right after that. Then we take size = 3 characters in
all, yielding "567".

By contrast, if you wrote,

"abcdefgh".slice(5, 10)

you will get "fgh", because we can't take any more characters after
"h" from the sequence.
