Javascript replacing double backslashed with single backslash

I have been browsing lots of solutions, but somewhy haven't got anything to work.

I need to replace following string: "i:0#.w|dev\\tauri;" with "i:0#.w|dev\tauri;"

I have tried following JS codes to replace:

s.replace(/\\\\/g, "\\$1");

s.replace(/\\\\/g, "\\");

But have had no result. Yet following replaced my \\ with "

s.replace(/\\/g, "\"");

To be honset, then I am really confused behind this logic, it seems like there should be used \\\\ for double backshashed yet it seems to work with just \\ for two backshashes..

I need to do this for comparing if current Sharepoint user (i:0#.w|dev\tauri) is on the list.

Update:

Okay, after I used console.log();, I discovered something interesting.

Incode: var CurrentUser = "i:0#.w|dev\tauri"; and console.log(): i:0#.w|dev auri...

C# code is following:

SPWeb theSite = SPControl.GetContextWeb(Context);
SPUser theUser = theSite.CurrentUser;
return theUser.LoginName;

JavaScript strings need to be escaped so if you are getting a string literal with two back slashes, JavaScript interprets it as just one. In your string you are using to compare, you have \t, which is a tab character, when what you probably want is \\t. My guess is that wherever you are getting the current SharePoint user from, it is being properly escaped, but your compare list isn't.

Edit:

Or maybe the other way around. If you're using .NET 4+ JavaScriptStringEncode might be helpful. If you're still having problems it might help to show us how you are doing the comparison.
