Callback when method finished

I want to execute method: bar() when method foo() is done.

This could be done like this:

function foo() {
  //....
  bar();
}

But there is surely some way to execute bar() like a callback to foo()? I have been looking in prototype API, but so far I only found ways to bind callbacks to HTML-elements...

Solution 
  • function foo(callback) {
   // ...
   callback();
}

    And then you call foo like this:

    foo(bar);
