Passing anonymous function as callback in Javascript

Question

Is there a way to pass anonymous function as a custom callback function in Javascript? I have this code:

function notifyme(msg){
    console.log(msg)
}

notifyme("msg", function(){
    //do some custom redirect logic    
});

I am trying the above code and it's executing notifyme function, but not going further with redirect code. I know I can pass a function name as a callback, but I don't have a specific function that I can pass. This is why they invented the anonymous function I guess.

It'd be really nice if there was a way to do that.

Your code pattern should be like

function notifyme(msg,callback){
    console.log(msg);
    // Do your stuff here
    if(callback){
      callback();
    }
}

notifyme("msg", function(){
    //do some custom redirect logic    
});
