Remove a specific set of characters from the end of the string with this line:
a.slice 0..-2
The command can be a little confusing. It tells Ruby to slice the string. This leaves only characters between 0, the first letter of the string, and -2, the next to last character of the string. This example would produce the string "hello there," with the last character "." removed.
