Import Assertions - Is This a Common J Script?

import assertions are an example of where we're getting functionality on top of the import mechanism, which does not exist in common j s. So i assert that what i'm importing is, rather than a java script vile, it's a jason file. And now i think they also support a caesa modules as something that you can import this way. But there have been lots of people who have said, why don't we just load up any anything, and it just comes in as a madul? I question about that though, because naively, i ask, why would i want to import jason rather than simply aronol,. Just downlod, use ajax
