Is this really true? It was my original assumption based upon string semantics. However, I was latter lead to believe that many engines don't routinely intern/canonicalize strings and hence string equality comparisons can't be assume to have the performance of pointer comparisons. For example, it was my understanding that SpiderMonkey uses interned strings for property lookup but that it doesn't necessarily intern non-property key strings??
