1.11 + File Name: 15.5.4.4-3.js
1.12 + ECMA Section: 15.5.4.4 String.prototype.charAt(pos)
1.13 + Description: Returns a string containing the character at position
1.14 + pos in the string. If there is no character at that
1.15 + string, the result is the empty string. The result is
1.16 + a string value, not a String object.
1.17 +
1.18 + When the charAt method is called with one argument,
1.19 + pos, the following steps are taken:
1.20 + 1. Call ToString, with this value as its argument
1.21 + 2. Call ToInteger pos
1.22 + 3. Compute the number of characters in Result(1)
1.23 + 4. If Result(2) is less than 0 is or not less than
1.24 + Result(3), return the empty string
1.25 + 5. Return a string of length 1 containing one character
1.26 + from result (1), the character at position Result(2).
1.27 +
1.28 + Note that the charAt function is intentionally generic;
1.29 + it does not require that its this value be a String
1.30 + object. Therefore it can be transferred to other kinds
1.31 + of objects for use as a method.
1.32 +
1.33 + This tests assiging charAt to a user-defined function.
