Is using jQuery the only way to modify the dom with JS?

I would like to talk more about jQuery's Flaw, and The Click Method.

can you talk more about why this is an error: $("h3events").click(turnEventsRandomColor());

I was stuck between b and d for answer 4, can you touch up on why we do not want to use the extra parentheses (turnBlue()) I am still a little confused on that part?

the reading made sense  / The reading was clear
