Socoder -> Web Development -> Is # ever used in JavaScript?

 		Quick question, and googling doesn't seem to answer this. Does the hash symbol (#) have any special meaning, anywhere, in JavaScript?

I'm presuming (and hoping) it's a complete no, but just want to check.

Thanks.

 		I've never seen it used, and my Javascript book doesn't have any reference to it in the index at all, so I think you're safe to use it.

Running this gives me the error:

Error: illegal character
Source File: jstest.html
Line: 2
Source Code:
#();


So I assume you're not allowed to use it?

 		I was wondering if it might be used for something else. For example @ is used for the pre-processor in JScript.

 		You can't have a # be a variable, like most languages.

You really should stick with letters, numbers, and underscores.

Quit posting and try Google.

 		I don't want to use it for variable names.

 		JL, what did you have in mind for the # symbols?

 		Considering the wide-spread usage of shebangs/hashbangs, I'd be tempted to say - being unable to find any evidence to the contrary - that they are fairly safe to use outside of this case. I couldn't find any mention of them in reserved symbols.
