    @ZnupiMar 26.2007 — [b]By BOM do you mean DOM????[/b]

    3. Then what is? window?... I think that document is the root object, considering that in Firefox, using FireBug, on the DOM tab the first thing is "document".

    4. I'm 90% certain the answer is true. Although there is VBScript and other sorts of client-side scripting languages, these are usually implemented only in Internet Explorer and they are never actually used...

    6. Why not? An event is an object itself, so if a. is true, b. must be true ?.

    7. False. It's needed rarely if you know how to code cross-browser.

    8. You probably mean "What would be an advantage", not "What would [b]not[/b] be an advantage"...

    10. Indeed false. There are browsers that can't handle javascript at all (for e.g. portable devices (PDA's) )

    I hope I'm right about this and not make a fool of myself, lol ?.

  • 3. The BOM is Browser Object Model and I am pretty sure, the root object is window.

  • 8. The question was original, and thanks for notice.
