Function called with Event Trigger

Question

I'm not sure why the function runs without being called. I only wanted to declare it for the button

Answer 1

Joshua Morgan ,
see this line 3:
test.addEventListener('click', doThis())

you shouldn't include parantheses () after function name doThis

It should be like this:
test.addEventListener('click', doThis);

because of parantheses function is called immediately and result `undefined` is returned to addeventlistener

your statement becomes
test.addEventListener('click', undefined)

hence it fails to work~

Oh my goodness I should really know better with my experience. Definitely not my first eventListener I promise! 😅
