How to execute a method passed as parameter to function

Question

I want to write my own function in JavaScript which takes a callback method as a parameter and executes it after the completion, I don\'t know how to invoke a method in my m

Answer 1

Another way is to declare your function as anonymous function and save it in a variable:

var aFunction = function () {
};

After that you can pass aFunction as argument myfunction and call it normally.

function myfunction(callbackfunction) {
    callbackfunction();
}

myfunction(aFunction);

However, as other answers have pointed out, is not necessary, since you can directly use the function name. I will keep the answer as is, because of the discussion that follows in the comments.
