It is possible. You would need to remove the curly braces as mention as well as the first semi-colon after "red". Currently when the JS engine reads this statement it ends before that closing parenthesis for the event listener. If you look in your console.log you will see the error "missing ) after argument list" since the statement ended before the closing parenthesis.

myHeading.addEventListener( 'click', () => = 'red' );
