    Using the method at 3:30, is it possible utilise parameters in the function? I notice that you wrote "changeColorOnMouseOver" instead of "changeColorOnMouseOver( )"
    Does this mean that I cannot use parameters in my functions?

    So the reason for 'the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute' is not because they are assigned using different way, but because even assigned using DOM will always occur after event assigned using HTML. So the latest assigned overwrites all previous assigned. Yes?

      I believe that's correct. The last event handler registered seems to win out: verified in Edge 38.14393.0.0, Firefox 50.0.1 and Chrome 54.0.2840.99 m (64-bit).

    Why this
    document.getElementById('btn').onmouseover = ChangeColorOnMouseOver
    and not this
    document.getElementById('btn').onmouseover = ChangeColorOnMouseOver() ?
    Why are there no parentheses behind the method ? what if we want to give an controlId as a parameter ?

      Because in example he use alert()
      He dont want to call this method when page loads.
      And you can pass parameters. I think after 5 months you managed to find answers :E
