Wondering 1.js & 0.js, what are they? SOLVED

Wondering 1.js & 0.js, what are they? Is because I install some 3rd packages?

There are two extra scripts come out on the head.

<script type="text/javascript" charset="utf-8" async="" src="http://localhost:3000/xx/wp-content/themes/s-theme/dist/scripts/1.js"></script>
<script type="text/javascript" charset="utf-8" async="" src="http://localhost:3000/xx/wp-content/themes/s-theme/dist/scripts/0.js"></script>

one of them looks like this:

It would appear so. You might want to find an alternative for skrollr. Looks like it’s quite outdated.
