Web Content Widget - adding JS

I am trying to create a Web Content widget and call custom js, trying to mimic the twitter embed example.

This is what I'm trying to do

<p id="quoteArea">loading...</p><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script><script>
$(document).ready(){
	getData();
}

function getData(){
	var apiUrl = "https://www.mocky.io/v2/56bb08b31300006d2d7cdfa5";
	
	$("#quoteArea").text("pulling data...");
	$.ajax({
	   type: 'GET',
		url: apiUrl,
		async: false,
		contentType: "application/json",
		dataType: 'jsonp'
	}).done(function( msg ) {
		$("#quoteArea").text(msg.result);
	});
}
</script>

1. Can I reference and use jQuery?

2. If not, what can I do with JS at the widget level?

Thanks!
