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
In this test, this is a String, pos is an integer, and
all pos are in range.
