If there is no character at that + string, the result is the empty string. The result is + a string value, not a String object. + + When the charAt method is called with one argument, + pos, the following steps are taken: + 1. Call ToString, with this 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 is or not less than + Result(3), return the empty string + 5. Return a string of length 1 containing one character + from result (1), the character at position Result(2). + + Note that the charAt 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. + + Author: christine@netscape.com + Date: 2 october 1997 +*/ +var SECTION = "15.5.4.4-2"; +var VERSION = "ECMA_1"; +startTest();
