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.
