Proper way for debug symbols in javascript

When i write javascript code , i usually insert a debug symbols to help me out .

Let me illustrate what i mean by example :

var debug = true;

/* Some event handler */
onValueChange = function(e, ui){
    var new_value = dom.volume.slider("value");
    conf.value = new_value;

    if (debug) {
        console.log("Value changed to : " + new_value);
    }
}

when i finish, i don't want all this debug related code to be part of my release/minified codebase . what is the convention for this sort of thing ? are there any (non IDE based) tools available ? I am looking for solutions working with exiting codebase and for starting a new project in the future .

Or what other debugging strategies exist in javascript world ?

To get rid of this logging code you will need to write a parser! I suggest that you go with a different debugging strategy. console.log is no doubt useful but a full fledged debugger like: the one provided by Chrome DevTools, is strongly advised. You can inject break points at any position in your code with debugger;. Going with a real debugger will make your life as a developer much more easier.
