jQuery $(this) selector not working.

$('.spoiler').on('click', 'button', (evt) => {
     //show the spoiler text 
    //hide the "reveal" 


I tried using various browsers. I am able to use $(evt.target) with no issues

Your code looks fine, though. I'd suggest to keep progressing with the lectures. You will know much more about the "this" keyword later on.

you will need to use function (e) {} instead of (e) => {}

From MDN: "An arrow function expression has a shorter syntax than a function expression and does not have its own this, arguments, super, or new.target."

I also highly recommend reading this article: http://2ality.com/2012/04/arrow-functions.html and this https://dmitripavlutin.com/when-not-to-use-arrow-functions-in-javascript/

The "this" that you are selecting in your arrow function expression is actually 'Window'.
