How to pass parameter to callback in javascript

Question

I would like to pass some parameter in call back like the following example. Is it a possible? Or I need to do it in another way?

function testCallback(callback, destination){
    // how can I pass the destination to callback
    callLib(callback)
}

function myCallback(destination){
    //do something
}

callLib is an external library that accept. I guess the interface should be like this

function callLib(callback){
    callback("something")
}

this one I think is not duplicate one. Sorry for my bad english. I have already change the question. see if you understand what the problem is

_"Is it a possible?"_ ? Have you tried it ? What did not work ? — Rayon, Jun 01 '16 at 04:10
Should it not be `callback(destination)` supposing you passed `myCallback` to `testCallback` — Sandeep Nayak, Jun 01 '16 at 04:10
callLib is an external library that I can only pass a callback with one parameter — travistam, Jun 01 '16 at 04:31
This one is not duplicate to the above. May be it is my enlist mistake — travistam, Jun 01 '16 at 04:35

I played with callbacks all day to learn how to do this. Here is some example code: https://stackoverflow.com/questions/37554672/jqueryui-dialog-doesnt-stop-code-to-wait-for-user-input/37556573#37556573
