| ECMA Section: 15.5.4.5 String.prototype.charCodeAt(pos) |
| Description: Returns a number (a nonnegative integer less than 2^16) |
| representing the Unicode encoding of the character at |
| position pos in this string. If there is no character |
| at that position, the number is NaN. |
| |
| When the charCodeAt method is called with one argument |
| pos, the following steps are taken: |
| 1. Call ToString, giving it the theis value as its |
| argument |
| 2. Call ToInteger(pos) |
| 3. Compute the number of characters in result(1). |
| 4. If Result(2) is less than 0 or is not less than |
| Result(3), return NaN. |
| 5. Return a value of Number type, of positive sign, whose |
| magnitude is the Unicode encoding of one character |
| from result 1, namely the characer at position Result |
| (2), where the first character in Result(1) is |
| considered to be at position 0. |
| |
| Note that the charCodeAt function is intentionally |
| generic; it does not require that its this value be a |
| String object. Therefore it can be transferred to other |
| kinds of objects for use as a method. |
