If positionis undefined or not supplied, 0 is assumed, so as to search all of the string. When the indexOf method is called with two arguments, searchString and pos, the following steps are taken: 1. Call ToString, giving it the this value as its argument. 2. Call ToString(searchString). 3. Call ToInteger(position). (If position is undefined or not supplied, this step produces the value 0). 4. Compute the number of characters in Result(1). 5. Compute min(max(Result(3), 0), Result(4)). 6. Compute the number of characters in the string that is Result(2). 7. Compute the smallest possible integer k not smaller than Result(5) such that k+Result(6) is not greater than Result(4), and for all nonnegative integers j less than Result(6), the character at position k+j of Result(1) is the same as the character at position j of Result(2); but if there is no such integer k, then compute the value -1. 8. Return Result(7). Note that the indexOf 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.
