Speed! VBScript vs JavaScript

[big_al]

Just wondering if anyone knew if there was a definite speed advantage to VBScipt as opposed to JavaScript?

Dont get me wrong but isnt VBScript only supported by IE

[Son Nguyen]

Yes, it's only supported by MS products.
However, about its speed, I don't think it matters, since when the code loaded into the client's browser, it's there very fast to execute, unlike server-side scripts.
Unless the VBscript/JS itself is huge (and that would not be the case with a normal web page!)

Hi,

As 123finder implies, the speed has more to do with the client's machine than anything else -- since the code will be running on the machine, not the server. As surpernovanetworks says: vbScript is primarily an IE product. Other browsers can run it only with a plug-in (which one I have no idea and don't really want to know, but I'm sure M$ has one out there). That implies extra processing time.

If you are worrying about response time, I would tweak the code itself, whatever the language. For example, in general, a switch statement would execute faster than a series of if/else statements. Also, external css & js files will speed processing -- if you require the same code in more than one page.

If, seem to be a moot point since like others before me have mentioned, only IE supports VBScript.

However in ASP files VBScript has demonstrated that it is a better performer in most areas compared to Javascript, but that's only Server side so its a little off-topic.

Hi duckie,

I'm presuming you mean ASP files that use javascript versus ASP files that use vbScript? What about ASP & M$'s version of javascript -- JScript -- does that also run faster than javascript? And if it does, I wonder why It can't be because ASP is tweaked, could it?

Oops...I of course meant JScript vs VBScript. My bad.

Hi duckie,

In that case I guess it's because M$ programmers aren't that concerned about JScript.
