1.11 + File Name: 15.5.4.5.1.js
1.12 + ECMA Section: 15.5.4.5 String.prototype.charCodeAt(pos)
1.13 + Description: Returns a number (a nonnegative integer less than 2^16)
1.14 + representing the Unicode encoding of the character at
1.15 + position pos in this string. If there is no character
1.16 + at that position, the number is NaN.
1.17 +
1.18 + When the charCodeAt method is called with one argument
1.19 + pos, the following steps are taken:
1.20 + 1. Call ToString, giving it the theis value as its
1.21 + argument
1.22 + 2. Call ToInteger(pos)
1.23 + 3. Compute the number of characters in result(1).
1.24 + 4. If Result(2) is less than 0 or is not less than
1.25 + Result(3), return NaN.
1.26 + 5. Return a value of Number type, of positive sign, whose
1.27 + magnitude is the Unicode encoding of one character
1.28 + from result 1, namely the characer at position Result
1.29 + (2), where the first character in Result(1) is
1.30 + considered to be at position 0.
1.31 +
1.32 + Note that the charCodeAt function is intentionally
1.33 + generic; it does not require that its this value be a
1.34 + String object. Therefore it can be transferred to other
1.35 + kinds of objects for use as a method.
