    You can just use both of them as $ in variable name has nothing to do with jquery. As long as you have a valid javascript variable name, you can use $ before your variable name.

    So for example :

    var $firstName = "ABC";

    and 

    var firstName = "ABC";

    when called in console.info() will output same things :

    console.info($firstName); // outputs "ABC" in firebug console.

console.info(firstName); // outputs "ABC" in firebug console.
