$(this) doesn't seem to be working

I'm having trouble getting the code here to work. Here's what I have.

$(document).ready(() => {
  $('button').click((event) => {
    $('button').removeClass('selected');
    $(this).addClass('selected');
  });               
});

The click is occuring and the removeClass function is working. (if I add perform $('button').addClass('selected') in the console, the buttons get selected and if I click then all the buttons get deselected), but the addClass isn't working. With a bit of troubleshooting it seems like $(this) is selecting the whole window and not the button.

Any ideas?

One of the differences between "arrow" functions and conventional functions is that arrow functions do not establish a value for "this". But for handlers you can use "event.target" instead.

See the details on all the differences on the Arrow Funcitons documentation page.
