| 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. | |
| 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 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). | |
| 24 | |
| 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. | |
| 29 | |
| 30 This tests assiging charAt to primitive types.. | |
