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.
