/**
File Name: 15.5.4.4-1.js
ECMA Section: 15.5.4.4 String.prototype.charAt(pos)
Description: Returns a string containing the character at position
pos in the string. If there is no character at that
string, the result is the empty string. The result is
a string value, not a String object.
When the charAt method is called with one argument,
pos, the following steps are taken:
1. Call ToString, with this value as its argument
2. Call ToInteger pos
3. Compute the number of characters in Result(1)
4. If Result(2) is less than 0 is or not less than
Result(3), return the empty string
5. Return a string of length 1 containing one character
from result (1), the character at position Result(2).
Note that the charAt function is intentionally generic;
it does not require that its this value be a String
object. Therefore it can be transferred to other kinds
of objects for use as a method.
