| michael@0 | 9 | ECMA Section: 15.5.4.4 String.prototype.charAt(pos) |
| michael@0 | 10 | Description: Returns a string containing the character at position |
| michael@0 | 11 | pos in the string. If there is no character at that |
| michael@0 | 12 | string, the result is the empty string. The result is |
| michael@0 | 13 | a string value, not a String object. |
| michael@0 | 14 | |
| michael@0 | 15 | When the charAt method is called with one argument, |
| michael@0 | 16 | pos, the following steps are taken: |
| michael@0 | 17 | 1. Call ToString, with this value as its argument |
| michael@0 | 18 | 2. Call ToInteger pos |
| michael@0 | 19 | |
| michael@0 | 20 | In this test, this is a String, pos is an integer, and |
| michael@0 | 21 | all pos are in range. |
