Add the class "strike" to the restaurant name each time it's double clicked. Use event delegation on the ul element to l

Hello, when I write:

$('ul').on('dblclick', 'li', (event) => { $(event.target).addClass('strike');
});

Everything is working perfectly. But when I write:

$('ul').on('dblclick', 'li', () => { $(this).toggleClass('strike');
});

It doesn't work anymore. The toggleClass doesn't change the CSS of the li element... What am I doing wrong?

Thanks!

Change your () => {} to function() => {}. I think now your code is working fine.

Huh, I ran into the same issue. Adam, any idea why the arrow syntax doesn't work?

I just have tips. Maybe the babel doesn't translate the code to es5, or your browsers doesn't support the es6 codes.
