In the ECMA 5 RC spec I noticed that 15.4.4.14 Array.prototype.indexOf (and lastIndexOf) make use of the SameValue operation. The spec states that (9.12) SameValue will return true If Type(x) is Undefined or Null.
Would this not cause an issue with 9c of the Array.prototype.indexOf spec. "c. If SameValue(searchElement,elementK) is true, return k.". [1,2,null].indexOf(null) -> SameValue(null, 1) -> true, return 0. var undef; [1,2,undef].indexOf(undef) -> SameValue(undefined, 1) -> true, return 0. - JDD _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
