Description Erik Arvidsson 2007-08-16 19:40:38 PDT 
Given an array where elements have been removed indexOf will match undefined to the deleted elements.

var a = [0, 1, 2, 3];
delete a[1];
a.indexOf(undefined)

test case coming...

Testcase

All text should be green
Comment 2 Mark Rowe (bdash) 2007-08-16 20:12:57 PDT 
Your test case gives me:

4
false
false
-1

All are green.  That would suggest we're already handling this correctly?

I strongly suspect this got fixed by my patch for bug 12963 and that the nightly used to test this was out-of-date.

Resolving as fixed per previous comments.
