How can we pass the event object, isn't that suppose to be in the scope of the event handler?
Secondly, we did not even mention that as an argument, so how the event caught is for the Input only? How the event Handler passed the event object.
Lastly, If I pass, It gives error, why so, the event is automatically being passed still?
messageTextArea.addEventListener('focus', focusHandler(e))

For more details, see the MDN page describing the event listener callback.
