  1. Thank you! Good video. So callback is just a placeholder when I want to be able to pass a function in to another function, then it acts as the function itself once we inject it in to the other function where we can substitute callback "in our minds" with the name of the function we passed in the code logic. Yay! I think I got it now!

  2. According to "design by contract" you should not check, if the passed value is a function as you don't check the other values either. I you pass garbage into a function then it's your own fault as a programmer.

  3. Thank you, thank you, thank you…..I thought i'd never understand "callback" function, I've watched a few videos on this subject and could not grasp it and nearly gave up……..but now……Thank you again.
