javascript - Bootstrap, jQuery, Popper, and CSS load order

Question

I'm not sure my load order is correct. Can someone make sure it is?

In "head" :

<link rel="stylesheet" type="text/css" href="css/bootstrap.css">
<link rel="stylesheet" type="text/css" href="css/style.css">

In "body" :

<script src="js/bootstrap.js"</script>
<script src="js/jquery-3.2.1.min.js"</script>
<script src="js/jquery-slim.min.js"</script>
<script src="js/popper.min.js"</script>
<script src="js/custom.js"></script>
