I want to hide an element with Alpine after X number of seconds. So I need to run a setTimeout() that changes an x-data variable that the element's x-show is bound to.

I'm currently using the script tag with normal JS in, but I can't seem to access the x-data variables from it.

As an example:

<div x-data="showSomething = true">
    <script>
        setTimeout(() => {
            this.showSomething = false;
        }, 1500);
    </script>
</div>

I get this error whether I use "this." or not:

Uncaught ReferenceError: showSomething is not defined

How can I access the x-data variables from normal JS, or is there a way to go about this in Alpine?

Edit: I solved this by using x-on to listen for the event (and referring to the variables without .this within that function)
