I had a discussion on the use of the === and !== operators recently on this list, my opinion was, and still is, that unless you explicitly WANT to allow type conversion, you should be using these. Only use == and != if you really want type conversion.
It's bitten me once, although I can't for the life of me remember how, but it involved lots of in-depth debugging and head-scratching to find the problem. I'm more wary now and think that these operators are the way to go. --rob On 8/2/07, Sam Collett <[EMAIL PROTECTED]> wrote: > > > I don't think many actually use !== (and when you would want to use > it) and many sites that show usage of operators don't cover !== (but > do have ===). > > 3 != '3' false > 3 !== '3' true > 3 == '3' true > 3 === '3' false > > > On Aug 1, 9:33 pm, "Michael Geary" <[EMAIL PROTECTED]> wrote: > > > I...cannot figure how what the heck === is. > > > > I see that Jake answered your question, but just for next time... > > > > You may have tried a Google search for "javascript ===" and been > > disappointed to find it returned no useful results (because Google seems > to > > ignore the === in the search). > > > > The key thing to know is that ===, like most special symbols in > JavaScript > > such as + and -, is an operator.
