The result is a string value, not a String object. + + If either argument is NaN or negative, it is replaced with zero; if either + argument is larger than the length of the string, it is replaced with the + length of the string. + + If start is larger than end, they are swapped. + + When the substring method is called with two arguments start and end, the + following steps are taken: + + 1. Call ToString, giving it the this value as its argument. + 2. Call ToInteger(start). + 3. Call ToInteger (end). + 4. Compute the number of characters in Result(1). + 5. Compute min(max(Result(2), 0), Result(4)). + 6. Compute min(max(Result(3), 0), Result(4)). + 7. Compute min(Result(5), Result(6)). + 8. Compute max(Result(5), Result(6)). + 9. Return a string whose length is the difference between Result(8) and + Result(7), containing characters from Result(1), namely the characters + with indices Result(7) through Result(8)1, in ascending order. + + Note that the substring 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: 12 november 1997 +*/ + +var SECTION = "15.5.4.10-1"; +var VERSION = "ECMA_1";
