Best practices for integrating external javascript?

Best practices for integrating external javascript?

I'm looking for some standard pieces of advice on how to integrate external JavaScript into a website. For example, on mywebsite.com:
<script src='//externalsite.com/js/script.js'></script>
The thing is: if externalsite.com gets hacked, mywebsite.com is at risk. And this JavaScript does not require access to the mywebsite.com content (it is for example a chatbox).
What would be the right way to do it? Is iFrame the way to go?
