+ File Name: 15.5.4.8-3.js
+ ECMA Section: 15.5.4.8 String.prototype.split( separator )
+ Description:
+
+ Returns an Array object into which substrings of the result of converting
+ this object to a string have been stored. The substrings are determined by
+ searching from left to right for occurrences of the given separator; these
+ occurrences are not part of any substring in the returned array, but serve
+ to divide up this string value. The separator may be a string of any length.
+
+ As a special case, if the separator is the empty string, the string is split
+ up into individual characters; the length of the result array equals the
+ length of the string, and each substring contains one character.
+
+ If the separator is not supplied, then the result array contains just one
+ string, which is the string.
+
+ When the split method is called with one argument separator, the following steps are taken:
+
+ 1. Call ToString, giving it the this value as its argument.
+ 2. Create a new Array object of length 0 and call it A.
+ 3. If separator is not supplied, call the [[Put]] method of A with 0 and
+ Result(1) as arguments, and then return A.
+ 4. Call ToString(separator).
+ 5. Compute the number of characters in Result(1).
+ 6. Compute the number of characters in the string that is Result(4).
+ 7. Let p be 0.
+ 8. If Result(6) is zero (the separator string is empty), go to step 17.
+ 9. Compute the smallest possible integer k not smaller than p such that
+ k+Result(6) is not greater than Result(5), 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 go to step 14.
+ 10. Compute a string value equal to the substring of Result(1), consisting
+ of the characters at positions p through k1, inclusive.
+ 11. Call the [[Put]] method of A with A.length and Result(10) as arguments.
+ 12. Let p be k+Result(6).
+ 13. Go to step 9.
+ 14. Compute a string value equal to the substring of Result(1), consisting
+ of the characters from position p to the end of Result(1).
+ 15. Call the [[Put]] method of A with A.length and Result(14) as arguments.
+ 16. Return A.
+ 17. If p equals Result(5), return A.
+ 18. Compute a string value equal to the substring of Result(1), consisting of
+ the single character at position p.
+ 19. Call the [[Put]] method of A with A.length and Result(18) as arguments.
+ 20. Increase p by 1.
+ 21. Go to step 17.
+
+Note that the split 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.
