ECMA Section: The String type
Description:
The String type is the set of all finite ordered sequences of zero or more
Unicode characters. Each character is regarded as occupying a position
within the sequence. These positions are identified by nonnegative
integers. The leftmost character (if any) is at position 0, the next
character (if any) at position 1, and so on. The length of a string is the
number of distinct positions within it. The empty string has length zero
and therefore contains no characters.
