Method; returns a 16-bit integer from 0 to 65535 that represents the character specified by index. If index is not a number from 0 to string.length - 1, NaN is returned.
This method is similar to String.charAt() except that the returned value is a 16-bit integer character code, not a character.

my_str = new String("Chris");
i = my_str.charCodeAt(0); // i = 67
