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. This tests assiging charAt to primitive types..
