The result has indices starting at 0 and length equal to high - low . This is great, as it gives us an easy way to perform slicing operations on the original value, and this is being performed super efficiently. A string type represents the set of string values. A string value is a (possibly empty) sequence of bytes. The number of bytes is called the length of the string and is never negative.
