title: What is the term for hosted JavaScript?
body: <p>I'm trying to find out what the terminology is that represents including JavaScript files that are hosted elsewhere. For example, there are payment gateway companies that will upon payment issue you a JavaScript file to include on a page of your application. This will render a payment UI on your site.</p>
  
  <p>What is the name of something like that? Hosted JavaScript is the only thing I can come up with but I'm pretty sure that's not correct because I can't find many resources after doing a search on that.</p>
