JavaScript from Null: Chapter 5 - Events

As we move forward with our JavaScript University, today, we'll learn how to add event handlers to elements on the page. Unfortunately, this can be more cumbersome than we'd hope, due to the fact that Internet Explorer must always be the black sheep. Nevertheless, we'll learn how to abstract these inconsistencies away to our custom utility function.

Can you do something like function addEvent(obj, evt, fn, capture = false) in declaration for default value?
