I’m hardly a JavaScript expert but I like to think my skills areabove average(although that could merely be wishful thinking).I won’t deny that JavaScript has its problems but I think that it has traditionally been maligned by things that aren’t necessarily the language’s fault; for instance, DOM inconsistencies are hardly under JavaScript’scontrol.
