8 File Name: 15.5.4.4-4.js
9 ECMA Section: 15.5.4.4 String.prototype.charAt(pos)
10 Description: Returns a string containing the character at position
11 pos in the string. If there is no character at that
12 string, the result is the empty string. The result is
13 a string value, not a String object.
15 When the charAt method is called with one argument,
16 pos, the following steps are taken:
17 1. Call ToString, with this value as its argument
18 2. Call ToInteger pos
19 3. Compute the number of characters in Result(1)
20 4. If Result(2) is less than 0 is or not less than
21 Result(3), return the empty string
22 5. Return a string of length 1 containing one character
23 from result (1), the character at position Result(2).
25 Note that the charAt function is intentionally generic;
26 it does not require that its this value be a String
27 object. Therefore it can be transferred to other kinds
28 of objects for use as a method.
30 This tests assiging charAt to primitive types..
