1.11 + File Name: 15.5.4.10-1.js
1.12 + ECMA Section: 15.5.4.10 String.prototype.substring( start, end )
1.13 + Description:
1.14 +
1.15 + 15.5.4.10 String.prototype.substring(start, end)
1.16 +
1.17 + Returns a substring of the result of converting this object to a string,
1.18 + starting from character position start and running to character position
1.19 + end of the string. The result is a string value, not a String object.
1.20 +
1.21 + If either argument is NaN or negative, it is replaced with zero; if either
1.22 + argument is larger than the length of the string, it is replaced with the
1.23 + length of the string.
1.24 +
1.25 + If start is larger than end, they are swapped.
1.26 +
1.27 + When the substring method is called with two arguments start and end, the
1.28 + following steps are taken:
1.29 +
1.30 + 1. Call ToString, giving it the this value as its argument.
1.31 + 2. Call ToInteger(start).
1.32 + 3. Call ToInteger (end).
1.33 + 4. Compute the number of characters in Result(1).
1.34 + 5. Compute min(max(Result(2), 0), Result(4)).
1.35 + 6. Compute min(max(Result(3), 0), Result(4)).
1.36 + 7. Compute min(Result(5), Result(6)).
1.37 + 8. Compute max(Result(5), Result(6)).
1.38 + 9. Return a string whose length is the difference between Result(8) and
1.39 + Result(7), containing characters from Result(1), namely the characters
1.40 + with indices Result(7) through Result(8)1, in ascending order.
1.41 +
1.42 + Note that the substring function is intentionally generic; it does not require
1.43 + that its this value be a String object. Therefore it can be transferred to other
1.44 + kinds of objects for use as a method.
