								You can also use <dfn>bracket notation</dfn> to get the character at other positions within a string.

								Remember that computers start counting at `0`, so the first character is actually the zeroth character.

								Let's try to set `thirdLetterOfLastName` to equal the third letter of the `lastName` variable using bracket notation.
