adding multiple types = click and focus to addEventListener

I have the same code applied to addEventListener ('click', =>){} and addEventListener ('focus', =>){}. Is there a way to combine click and focus in one addEventListener to avoid doubling the code? Could it be a function?

You have to set a separate listener for each event type. But they could share the same handler function, just define it separately and name it when you set the listener.

let hander = e => { /* handler code */ };
myElement.addEventListener('click', handler);
myElement.addEventListener('focus', handler);
