| 8 File Name: 15.5.4.4-1.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. | |
| 14 | |
| 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 | |
| 20 In this test, this is a String, pos is an integer, and | |
| 21 all pos are in range. | |
