[How to bind animation start to browser event?]

Hello everyone!

 

Can anybody explain me why this variant of binding works

document.querySelector('.burger').addEventListener('click', _ => {
  burgerLine.play()
})

and this one

document.querySelector('.burger').addEventListener('click', burgerLine.play)

causes the following error
